MS5000 Outdoor Finnish Sauna
The MS5000 is a large outdoor Finnish sauna built for people who take heat bathing seriously. This is not a summer-only piece of garden furniture. It is a permanent outdoor structure — engineered for year-round use in the British climate, delivered and installed by our own team, and guaranteed for the life of the building.
Traditional hot-stone heat. A 6kW heater is included as standard, bringing the stone bed to temperature and radiating deep, dry heat through the cabin. Ladle water across the stones and the humidity lifts sharply — the löyly that defines a genuine Finnish session. Higher-output heaters, including Wi-Fi enabled models, are available as priced upgrades.
Built for outdoors. The structure is specified for permanent external installation — treated timber, weather-sealed joins, and a professional-grade frame designed to expand and contract seasonally without compromising the cabin. We assess every installation site before we confirm the order to check base, access, and electrical supply.*
Red light therapy upgrade available. Add a full red light therapy installation for £999 — fitted alongside the sauna by the same team on the same day.

Frequently asked questions
Do I need planning permission for an outdoor sauna?
Generally no — a detached garden structure under 2.5m in height that covers less than 50% of your garden does not typically require planning permission under UK permitted development rules. We recommend checking with your local authority if you are in a conservation area. We can advise at the assessment stage.
What base do I need?
A level concrete pad or solid treated decking is standard. We will confirm base requirements during the pre-installation assessment.
What electrical supply does it need?
A dedicated 32A circuit is standard for this model. Electrical connection must be carried out by a qualified electrician with Part P certification — we can include this in your installation quote.
What does the lifetime guarantee cover?
The structural guarantee covers the frame, cladding, benching, and glass against structural defects for the lifetime of the sauna. Electrical items — heater, controls, and lighting — are covered for 2 years.
Is the red light therapy upgrade worth adding?
For most clients, yes — adding it at installation is significantly cheaper and cleaner than retrofitting later. It is installed inside the cabin and can be used independently of the sauna heat.
Built to last. Guaranteed for life.
Every Medi-Spa sauna carries a full lifetime guarantee on structural defects — the frame, cladding, benching, and glass, for as long as you own it. Electrical items are covered for 2 years as standard.
0% finance available on orders from £7,500 — subject to status. T&Cs apply.
* Pre-installation assessments are carried out in person for clients within our local area. For clients further afield, we conduct a thorough remote assessment using photos, video and plans — at no charge and with no obligation to proceed.
