A home built-in sauna is the must have this year. 

We have a great relationship with a team of local master builders and utilise their skills for clients wishing to have a luxury sauna built inside their house. 

Our team works strictly to the building code, can assist with all stages of the planning and build of your dream home sauna. We don’t offer corner cutting or even the cheapest price, instead focusing on a healthy sauna done right. 

We can accept work from clients who already have building consent and plans in place, or start the process from scratch with our recommended architect, working with them to get the sauna through the consenting process. 

As a rough guide to costs involved. 

If building consent is required: Architect – full design and putting plans through council ($250 per hour, plus any applicable council fees). 

If building consent in place or not required: Builder and Sauna advisor site visit $450 (refundable if we build the sauna). There is a 2 week lead time on this process. Room/heater plans can be produced and a quote provided at this point. 

Sauna room:  Assumes no changes to outer building envelope and a maximum 2.3 meter stud height. 

Starting from exposed vertical framing already in situ. Includes specialist wool insulation, vapour permeable/waterproof rigid air barrier, flashings, tanking, floor leveling compound, tiling laid (client provides own 600mmx600mm or 450mmx450mm tiles), 10mm safety glass door with self closing hydraulic hinges, cavity battens, vents, western red cedar tongue and groove wall/ceiling linings and bench seats. We use low VOC building materials specific to sauna and stainless steel fastenings.
