SAUNA PRICES
Sauna Prices London 2026
Every sauna is different. Every price is honest.
We've been building bespoke saunas in London since 2010. In that time we've built them in disused WCs, loft conversions, garden sheds, basement gyms and pool houses — no two the same. Which means we know better than most that giving you a single price for a sauna is a bit like giving you a single price for a kitchen extension. It depends on the space, the specification, and what the sauna is actually going to do for you.
What we can do is be completely straight with you about what drives the cost — and give you real guide prices.

We get asked regularly if we can do something cheaper...
Our regular answer is: cheaper than what?
Cheaper than a properly ventilated, properly insulated, properly built sauna? Yes, you can find that. There are companies who will build you a sauna in a day for £5,000. There are prefab kits from Finland that you can assemble yourself. Some of them are fine.
But a sauna that doesn't ventilate correctly doesn't deliver the cardiovascular and cognitive benefits that 20 years of Finnish research has documented. It delivers a hot, stuffy room that you stop using. We've been called in to fix a fair number of those.
Our starting price of £7,995 is not a marketing number. It is the minimum to deliver a sauna that performs as a sauna should — with the ventilation designed properly, the materials specified correctly, and the workmanship to last.
Everything above that starting point is about what you want the sauna to be: the type, the size, the timber, the technology, and the finishing. That's a conversation we look forward to having.
What you get in a bespoke sauna that you don't get in a flat-pack.
Wood Quality & Selection
Bespoke:
Hand-selected premium timbers — Thermowood Aspen, Natural Alder, Nordic White Spruce, or African Abachi — chosen for grain consistency, knot-free surfaces, and low resin content. Wood is often kiln-dried to precise moisture levels and may be sourced from a single log batch for colour uniformity.
Readymade:
Typically spruce or hemlock of mixed grade. Knots, grain variation, and inconsistent drying are common. Fine for function, but noticeable up close.
Joinery & Construction
Bespoke:
Tongue-and-groove boards with micro-bevelled edges, hand-fitted and face-fixed with hidden fixings. Corners are properly mitred or box-jointed. The bench framework uses mortise-and-tenon or dowel joinery — built to last decades.
Readymade:
Flat-pack panel construction with visible screws, staples, and bracket connectors. Boards may bow or gap over time as the wood cycles through heat.
Heater Matching & Integration
Bespoke:
The heater is specced precisely for the room's volume, insulation quality, and your usage pattern. Wiring is concealed, controls are flush-mounted or wireless, and the stone load is hand-selected (not just "rocks in a bag").
Readymade:
Heater is bundled to hit a price point, often slightly underpowered or oversized for the cabinet. Budget wiring and inferior feeling controls are standard.
Insulation & Thermal Performance
Bespoke:
Rock wool or foil-backed mineral insulation between studs, vapour barrier properly lapped and taped, and an air gap managed for longevity. Reaches temperature faster and holds it more evenly.
Readymade:
Thin foil lining stapled to the interior. Heat loss is higher; hot and cold spots are common; humidity control is less precise.
Benches & Ergonomics
Bespoke:
Benches are designed around your body — height, depth, and angle adjusted for you. Backrest rake, leg clearance, and two-tier positioning are all considered. Rounded edges, wider boards, and a smoother finish can be added.
Readymade:
Fixed bench heights and depths, huge gaps between typically narrow boards (60 - 70mm), sharp edges unless sanded down, and no real ergonomic thought.
Ventilation Design
Bespoke:
Fresh air intake and exhaust positioned by a builder who understands sauna thermodynamics — typically low intake behind the heater, high exhaust on the opposite wall. Creates a proper convection loop.
Readymade:
Often a simple vent in the door or a basic grille. Stale air buildup and uneven heat distribution are common complaints.
Lighting & Atmosphere
Bespoke:
Recessed LED sauna lighting (rated for saunas), under-bench mood lighting, possibly contemporary LED wall panels. Switches and dimmers are integrated cleanly within the sauna controls and can be operated through W-Fi.
Readymade:
A bulkhead light behind a plastic guard. Functional, nothing more.
Door & Glass Panels
Bespoke:
Full glass door (8–10mm toughened), solid wood frame, quality stainless or wooden handle, and magnetic or wooden latch that seals properly.
Readymade:
Thinner glass or part-glass doors, cheaper frames, and latches that often need adjustment after a few months of use.
Longevity
A well-built bespoke sauna, properly maintained, will comfortably last 30–40 years. A £5k readymade, realistically, is a 5–10 year product - and it'll start looking tired after five.
The Honest Summary:
The £5k sauna will make you sweat eventually, just not as effectively. You're paying the bespoke sauna premium for how it feels to be in it, how it looks in your home, how long it lasts, and the confidence that every detail was thought through. If you use it daily, the bespoke cost per session over its lifetime is actually lower.
