How much does a custom garden sauna cost? 2026 prices and what they depend on

In 2026 a quality custom garden sauna costs from around PLN 20,000-30,000 (approx. EUR 4,700-7,000) upwards, and larger saunas with a changing room or a lounge area usually come to PLN 50,000 (approx. EUR 11,600) or more. The simplest uninsulated barrels with a heater cost from around PLN 16,000-17,000 (approx. EUR 3,700-4,000), but they are a different class of product, intended more for seasonal use. The final price of a custom sauna depends on the size, the glazing, the heater, the wood and the location, which is why at tusauna.pl we price every sauna individually, based on your enquiry.

Where does a quality sauna start?

From around PLN 20,000-30,000 (approx. EUR 4,700-7,000) for an insulated sauna for 4-6 people with a good heater, built and installed by a professional team. That matches what we see among our clients: people looking for a sauna for PLN 10,000-15,000 (approx. EUR 2,300-3,500) usually buy home-made structures and organise the installation themselves, while those who want a sauna that lasts for years plan from the start for PLN 20,000-30,000 (approx. EUR 4,700-7,000) or more, depending on the size, glazing, heater and finish.

The most satisfying question to ask is “what should be inside”, not “what is the cheapest option”. A sauna where the whole family can sit comfortably and which heats up quickly in winter is an investment for years, not for one season.

What does the price of a custom sauna depend on?

We set the price of a custom sauna once we know the location, the number of people and the equipment, because each of these decisions shifts the cost by thousands of zloty. That is why we have no “prices from” list; instead we take an individual approach and agree everything directly with you. The main components of the price:

• Size and bench layout. A larger interior means more material and a more powerful heater. We translate the number of people into a real size, so you do not pay for space you will never use.
• Glass. A glazed wall gives a beautiful view but needs a more powerful heater, because every square metre of glass means about 1.2 kW more power.
• Heater and controls. Good 9 kW heaters from well-known brands cost around PLN 1,300-2,600 (approx. EUR 300-600), and premium heaters with a large mass of stones around PLN 7,500-10,000 (approx. EUR 1,700-2,300). App control is an extra cost that makes winter use much easier.
• Wood. The species used for the benches, interior panelling and exterior changes both the price and the character of the sauna. Thermally modified wood costs more than spruce, but it is more stable and has a dark, elegant colour.
• Insulation and construction. Insulated walls and ceiling with aluminium foil are the foundation of a sauna that works all year round.
• Extras. A changing room, lighting, a canopy over the entrance, hooks, an extra window.
• Location and access. The distance, how the elements are carried in and the preparation of the base.

If the budget needs adjusting, we suggest cutting back on extras rather than on the size of the sauna. Extras can be added later; the walls cannot be moved.

What does the price of a tusauna.pl sauna include?

At tusauna.pl we handle the whole process: design, choice of materials, preparation of the elements, installation on site and handover. We prepare the elements specifically for your sauna, and on your plot we usually assemble them in one working day. Transport and installation are agreed individually in the quote, depending on the location and the design.

As part of the project we:

• design the size, bench layout and glazing to suit your location,
• match the heater to the volume and the glass,
• carry the elements in by hand, with no crane,
• install the sauna, heater, controller and lighting, and connect the electrics,
• carry out the first heating, the handover and a walkthrough of how to use it.

On your side, you prepare the base, and we agree the details of the base and power supply directly with each order. From signing the contract to a finished sauna usually takes from 6 weeks to 3 months; the deposit is 20%, and the rest is paid after handover.

Is the price of the sauna fixed?

Yes. Once we have confirmed the terms and the specification, the price does not change. That is why we put so much care into the first enquiry and the design: all decisions are made before the contract, not during installation.

How much does site preparation cost?

Preparing the base is usually a small part of the budget. A garden sauna is a light building, so it does not need foundations like a house. Concrete blocks on a layer of aggregate or a slab are usually enough. We agree the details directly with each order, and you can read more in our guide to preparing the site.

How much does it cost to maintain a sauna?

Very little: the benches are treated with paraffin oil every 1-3 years, the heater stones are replaced once a year with regular use, and the exterior is refreshed with oil every few seasons. At handover we show you how to look after the sauna so that it looks and works for years just as it did on installation day.

Is it worth buying a second-hand garden sauna?

A used sauna can be cheaper, but it rarely fits a specific location, and its condition after a few winters does not show in a photo. You also have to arrange to move it in one piece, which usually means a crane and wide vehicle access. A custom sauna is made from the start for your location and the people in your home, and we carry the elements in through an ordinary garden gate.

Now that you know what drives the price, the simplest next step is to find out what your sauna would cost.
