Are Home Saunas Worth It? UK Costs, Benefits and Buying Guide

Home saunas are becoming an increasingly popular addition to UK homes, but are they genuinely worth the investment?

For people who expect to use one regularly, a home sauna can offer excellent long-term value. It provides a private space for relaxation, post-workout recovery and quiet time without the cost or inconvenience of visiting a gym, spa or public sauna. However, its value depends on choosing the right model, having a suitable installation space and being realistic about how often it will be used.

This guide examines the benefits, costs and practical considerations to help you decide whether buying a home sauna is right for you.

 

Quick answer: is a home sauna worth it?

A home sauna is likely to be worth it if you:

• Plan to use it several times a week
• Value privacy and convenience
• Regularly pay for spa visits or gym facilities
• Have enough indoor or outdoor space
• Can accommodate the required electrical connection
• Want to create a permanent home wellness space

It may offer less value if you only expect to use it occasionally, have limited installation space or are unsure which type of heat experience you prefer.

Why are home saunas becoming more popular in the UK?

Once associated mainly with Nordic countries, saunas are now becoming a more familiar feature in British homes and gardens.

Interest is being driven by the growth of home wellness, garden rooms and dedicated recovery spaces. More people also want convenient ways to relax without travelling to a spa or relying on a gym’s opening hours.

This is not simply an online trend. The Guardian reported on the growth of home saunas in Britain, highlighting rising demand for indoor, outdoor, traditional and infrared models.

The UK climate may also make ownership particularly appealing. A warm, private sauna can be enjoyed throughout the year, including during colder and darker months when outdoor leisure spaces might otherwise go unused.

What are the main benefits of owning a home sauna?

The clearest benefits are convenience, privacy and the ability to establish a regular routine.

Convenient access at any time

Having a sauna at home removes the need to book a session, travel to a spa or wait for a shared sauna to become available. You can use it when it fits your schedule, whether that is after exercise, at the end of the working day or during a quiet weekend.

That convenience matters because a wellness feature only provides value when it is used. Easy access can make it much simpler to turn occasional sauna bathing into a consistent routine.

A private place to relax

Public saunas are not comfortable for everyone. A home model gives you control over the environment, including the temperature, lighting, music and length of your session.

It can become a dedicated space away from phones, work and everyday distractions. For couples and families, a larger cabin can also provide a calm space to spend time together.

Warmth and post-exercise comfort

Many people enjoy a sauna after training because the heat can feel soothing on tired or tight muscles. It may be a pleasant part of a wider recovery routine alongside hydration, rest, sleep and sensible exercise programming.

A sauna should not, however, be presented as a treatment for an injury or a replacement for medical care.

A choice of heat experiences

Home saunas are available with different heating systems, allowing buyers to choose the experience that suits them best.

Traditional saunas heat the surrounding air and can produce bursts of steam when water is added to suitable heated stones. Infrared saunas use infrared energy to warm the body more directly and normally operate at a lower air temperature. Hybrid saunas combine both options in one cabin.

According to the Mayo Clinic’s explanation of infrared saunas, people may experience sweating and an increased heart rate at lower air temperatures than in a conventional sauna. The organisation also notes that although research has identified possible health benefits, larger and more precise studies are still required.

The most responsible way to view a home sauna is therefore as a relaxation and lifestyle product, rather than a guaranteed treatment for a medical condition.

What types of home sauna are available?

The right option depends on the heat experience you want, where the sauna will be installed and the available electrical supply.

Infrared saunas

Infrared panels warm the user directly rather than relying entirely on heating the surrounding air. These cabins usually operate at lower temperatures than traditional saunas and tend to heat up relatively quickly.

An infrared sauna may suit someone who:

• Prefers gentler ambient heat
• Wants an indoor sauna
• Has limited space
• Values a shorter preheating time
• Finds very high temperatures uncomfortable

Electrical requirements vary by model, so never assume that every infrared sauna can use a standard plug.

Traditional steam saunas

A traditional sauna uses an electric or wood-burning heater to heat the cabin and sauna stones. Where the heater is designed for it, small amounts of water can be poured onto the stones to create a brief increase in humidity known as löyly.

Traditional saunas are often chosen by people who want:

• A hotter air temperature
• The familiar Finnish-style sauna experience
• Heated stones and bursts of steam
• A strong, enveloping heat

Electric heaters frequently require a dedicated circuit and hardwired connection. The exact requirements should always be checked before purchase.

Hybrid saunas

A hybrid or combination sauna includes infrared panels and a traditional heater in the same cabin. This lets users choose between lower-temperature infrared warmth and a more traditional high-heat session.

Hybrid models are generally more expensive, but they can offer better value for households where different users prefer different types of heat.

Indoor and outdoor saunas

Indoor saunas work well in suitable bathrooms, spare rooms, home gyms and dedicated wellness areas. The room must have the necessary space, ventilation, flooring and electrical supply for the selected model.

Outdoor saunas create a separate garden retreat and are available in cabin, barrel, cube and other designs. They normally require a stable, level base and a safely installed power supply. Weather protection, drainage, access and the route of the electrical cable should all be considered before ordering.

You can compare indoor, outdoor, infrared, traditional and hybrid options in the CenturaHeat sauna collection.

How much does a home sauna cost to run in the UK?

The running cost depends on four main factors:

1. The sauna’s power rating in kilowatts
2. How long it takes to heat
3. How long the session lasts
4. Your electricity unit rate

A simple estimate can be calculated using:

Power in kW × hours used × electricity price per kWh

For example, using the average Ofgem electricity rate of 26.11p per kWh from 1 July to 30 September 2026, the maximum theoretical electricity cost would be approximately:

These are illustrative figures, not guaranteed session costs. Once the target temperature is reached, a thermostatically controlled heater may cycle rather than draw its maximum power continuously. Outdoor temperature, cabin insulation, warm-up time and door opening can also affect consumption.

The daily electricity standing charge should not normally be added to the calculation because a household already pays it regardless of whether the sauna is used.

Before buying, check the exact kW rating on the individual product page and use your own electricity tariff to estimate the likely cost.

Is an infrared sauna cheaper to run than a traditional sauna?

Infrared cabins are often cheaper per session because they commonly have a lower power rating and heat the user at a lower air temperature. That does not mean every infrared model will cost less than every traditional sauna.

Cabin size, insulation, session length and heater output all affect consumption. A small, well-insulated traditional sauna may cost less to use than a large infrared cabin left running for a longer period.

The fairest comparison is to use the stated power rating and expected running time of the exact models you are considering.

How much space does a home sauna need?

Compact one and two-person saunas can fit into relatively modest indoor areas, while larger family and outdoor models require substantially more room.

Do not compare external dimensions alone. You should also allow space for:

• The sauna door to open fully
• Safe access around the cabin
• Ventilation
• Electrical connections
• Assembly and future maintenance
• A suitable base or floor
• Any manufacturer-specified clearances

Measure the complete route from the delivery point to the installation area. Doorways, staircases, tight corners, gates and narrow side passages can create problems even when the finished sauna fits comfortably in its intended position.

What electrical work does a home sauna require?

Electrical requirements depend on the heater and total power demand.

Some lower-powered indoor models may operate from a suitable socket, while higher-powered traditional and hybrid saunas generally require a dedicated circuit and hardwired connection. This work should be completed by a qualified electrician in accordance with the manufacturer’s instructions and current UK electrical requirements.

Before ordering, confirm:

• The voltage and total power rating
• Whether the sauna is plug-in or hardwired
• The required circuit and protective devices
• The cable route
• The position of the isolator
• Whether the supply is single-phase or three-phase
• Who is responsible for making the final connection

Do not purchase based on the assumption that a sauna uses a normal household plug. Always check the specification for the individual model.

Do outdoor saunas need planning permission?

Many garden saunas may fall within permitted development rules, but this is not automatic.

Planning requirements can depend on the sauna’s height, location, proximity to boundaries, the amount of land covered by outbuildings and whether the property is listed or situated in a designated area. Building regulations, electrical work and smoke-control restrictions may also be relevant.

Check with your local planning authority before installing an outdoor sauna, particularly if you are considering a large structure or wood-burning heater.

How much maintenance does a home sauna need?

Saunas are generally straightforward to maintain when cleaned regularly and allowed to dry properly.

Basic care includes:

• Sitting on a clean towel to reduce sweat reaching the benches
• Wiping benches and frequently touched surfaces
• Allowing the cabin to air and dry after use
• Avoiding harsh household chemicals on sauna timber
• Cleaning glass with an appropriate product
• Checking heaters, stones and electrical components as instructed
• Replacing damaged or deteriorated sauna stones when necessary
• Following the manufacturer’s maintenance schedule

Outdoor cabins may also need periodic checks of the roof, seals, exterior timber and weather protection.

Who is a home sauna best suited to?

A home sauna can be particularly worthwhile for:

• Regular sauna users
• Couples or families who will share it
• People creating a home gym or wellness room
• Those who value private relaxation
• Fitness enthusiasts who enjoy heat after training
• Homeowners with unused indoor or garden space
• People who currently spend regularly on spa sessions

The financial value becomes stronger as the number of users and sessions increases. A cabin used by two people several times a week is easier to justify than one used by a single person every few months.

When might a home sauna not be worth it?

A home sauna may not be the right purchase if:

• You have never tried sauna bathing
• You dislike prolonged heat
• The available space is unsuitable
• Electrical work would be unusually difficult
• You expect to use it infrequently
• The purchase would put pressure on your household budget
• You are moving home soon and cannot take the sauna with you

If you are unsure, visit a reputable spa or public sauna several times first. Try both infrared and traditional heat if possible. This can help you avoid choosing a model based solely on appearance.

Are home saunas safe?

Most healthy adults can use a sauna sensibly, but heat exposure is not suitable for everyone.

Stay hydrated, avoid alcohol before and during use, and leave immediately if you feel dizzy, faint, nauseous or unwell. Beginners should start with shorter sessions and moderate temperatures rather than trying to tolerate the hottest setting.

Seek medical advice before using a sauna if you are pregnant, have a cardiovascular condition, experience unstable blood pressure, take medication that affects heat tolerance or have any other relevant health concern. A sauna is not a substitute for medical treatment.

How to decide whether a home sauna is worth it for you

Before making a decision, ask yourself:

1. How many people will use it?
2. How many sessions are realistically likely each week?
3. Do we prefer infrared or traditional heat?
4. Where will the sauna be installed?
5. Is there a suitable electrical supply?
6. What installation work is required?
7. What will each session cost using our tariff?
8. Is the cabin covered by a suitable warranty?
9. Can it be delivered to the intended location?
10. Would we use it more than a gym or spa sauna?

If your answers point to frequent use, suitable space and manageable installation costs, a home sauna can be a worthwhile long-term addition.

Final verdict: are home saunas worth the money?

Yes, a home sauna can be worth the money for someone who enjoys sauna bathing and expects to use it regularly.

Its greatest value comes from convenience. Instead of arranging trips to a spa or choosing a gym based on its facilities, you have private access at home whenever it suits you. Over time, that can make it easier to maintain a consistent relaxation or post-workout routine.

However, the right model matters. Compare the heating system, capacity, electrical requirements, installation needs, warranty and running costs rather than choosing on price alone.

Frequently asked questions

Is a home sauna a good investment?

It can be a good lifestyle investment if it will be used regularly. Its value comes primarily from convenient, private access rather than guaranteed financial returns or an increase in property value.

How much does it cost to run a home sauna?

Multiply the sauna’s kW rating by the number of hours used and your electricity unit rate. At 26.11p per kWh, a 4.5kW heater running continuously for one hour would use about £1.18 of electricity. Actual consumption may be lower when the thermostat cycles the heater.

Is an indoor or outdoor sauna better?

An indoor sauna offers easy access and protection from the weather. An outdoor sauna can provide more room and create a separate garden retreat. The better option depends on your available space, preferred design and installation requirements.

What is the best sauna for home use?

Infrared saunas suit people who prefer gentler temperatures and a straightforward indoor setup. Traditional saunas provide hotter air and the classic stone-heater experience. Hybrid models offer both options but usually cost more.

Does a home sauna add value to a property?

A well-installed sauna may make a property more appealing to certain buyers, but an increase in sale price is not guaranteed. It is better to buy one for your own regular enjoyment than to rely on it as a property investment.

How often can you use a home sauna?

There is no single frequency suitable for everyone. Beginners should start gradually with shorter sessions and see how their body responds. Some experienced users sauna several times a week, but comfort, hydration, health and manufacturer guidance should determine your routine.

Can you put a sauna in a spare room?

Potentially, provided there is enough space, suitable ventilation, an appropriate floor and the required electrical supply. Check all installation instructions and consult a qualified electrician before committing to the location.

Do home saunas require a lot of maintenance?

Usually not. Regular wiping, ventilation and drying form the basis of routine care. Traditional heaters and sauna stones may require additional inspection or maintenance according to the manufacturer’s instructions.
