The Baltresto Solo Vertical Outdoor Sauna is a compact, one-person sauna built entirely from durable thermowood. Its upright design takes up a footprint of just 120 x 124 cm, making it a perfect fit for private gardens, terraces and smaller outdoor spaces where a barrel sauna would be too large. A transparent tempered glass front wall and glass door come as standard, giving you an open, light-filled steam room and a clear view of your garden while you relax. Choose between a Harvia The Wall SW45 or a Huum Drop 4 electric heater to suit your style.

Launch offer: 20% off until 15 December 2026. From 16 December the price returns to £2,699.

Features

Compact Footprint - Designed for Small Spaces

The vertical layout gives you a full sauna experience in a footprint of 120 x 124 cm, so it fits neatly on a patio, terrace or corner of the garden without dominating the space.

Open Up the View - Glass Front Wall and Door as Standard

A transparent tempered glass front wall and matching glass door come included, filling the steam room with natural light and turning every session into a view of your garden.

Fast, Efficient Heat - Harvia or Huum Electric Heater

With a steam room volume of around 2 m³, the Solo heats up in under an hour. Choose between the slim, wall-mounted Harvia The Wall SW45 (4.5 kW) or the striking Huum Drop 4 (4 kW) for even, comfortable heat.

Built to Last - Thermowood Throughout

The entire sauna body is made from 39 mm thermowood, which is heat treated for a rich natural colour and excellent resistance to moisture, weather and rot.

Comfortable and Relaxing - Alder Bench

A 49 cm wide alder bench stays smooth, cool to the touch and splinter-free in the heat, giving you a comfortable seat for longer sessions.

Weatherproof Finish - Bitumen Shingle Roof

A black bitumen shingle roof with roof angles protects the sauna from rain and gives it a clean, modern finish.

Delivery

This sauna is custom-made to order. Delivery times will be confirmed at the time of ordering.

For assembled orders, the buyer is responsible for unloading the goods from the truck using a crane or forklift. Please ensure the truck can access the unloading area without any obstructions and inform us of any access restrictions at the time of ordering. Unloading will take place at the site boundary (usually on the pavement) or as close as possible, depending on local conditions.

Base Requirements

A solid, level base is required before installation. We can provide the sauna's foot arrangements on request to help with preparing the base.

Electrical Setup

A qualified electrician is required to set up the power supply for the electric heater. Please check the supply requirements of your chosen heater before ordering. Heaters are supplied uninstalled, and the connection cable is not included.

Warranty

  • Private Use: 2-year factory warranty for residential use.
  • Commercial Use: 6-month warranty, valid when used as per manufacturer guidelines.

The warranty period starts from the date of delivery and covers manufacturing and material defects, provided the sauna is used correctly and in line with the provided instructions. If ordering a sauna as a kit for assembly, the warranty applies to the supplied components, not the assembled product. Saunas must be assembled and installed within two weeks of delivery to remain under warranty.

The warranty does not cover damage caused by improper installation, maintenance or storage; natural wear and tear or mechanical damage; incorrect handling; modifications or unauthorised repairs; natural material characteristics (e.g. wood cracks, discolouration, shrinkage); or extreme weather conditions.

Receiving Your Sauna
Upon delivery, please inspect your sauna for transport damage before signing. If damage is found, note it on the shipping document, take photos and report it to us within 7 days of delivery.

Cancellations
You may cancel your order before production begins for a full refund by informing us in writing. As our saunas are made to order, cancellations, refunds and returns are not possible once production has started.
