MS5000 Finnish Sauna
Heating system: Traditional hot stone
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, with optional installation by our own team, and backed by a lifetime structural guarantee.
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?
Whether planning permission is needed depends on the height of the structure, how close it sits to your boundary, and how much of your garden it covers. Many garden structures fall under permitted development, but a cabin taller than 2.5 m, or one sited close to a boundary, can need permission. The MS5000 stands 253 cm tall. Please check with your local authority, especially 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 MS5000 carries a lifetime structural guarantee on the frame, cladding, benching and glass. Electrical components are covered for 2 years. Contact info@medi-spa.co.uk for any warranty enquiry.
