Delta

Seven Delta steam generators, $2,470 to $12,009, median $4,012. This is a parts collection, not a cabin collection — every unit here is the generator alone, 5kW to 30kW, specified to go into a shower enclosure you already have or are building.

Sizing a generator

A steam generator is matched to the volume of the enclosure, not to the size of the room or the number of people. Ceiling height counts, and so does what the walls are made of: tile over cement board holds heat, and glass and stone lose it, so an identical footprint can need a larger unit. Get the cubic footage before you shortlist anything here.

What has to be there already

A generator needs a sealed enclosure with a vapour-proof door, a water supply and a drain, and a dedicated circuit — one of the seven names 240V explicitly and the rest depend on the model, so confirm the electrical spec against the unit before you buy. The generator itself usually sits remote, in a vanity, closet or basement within a set pipe run of the head. If that space does not exist, the install cost is a wall, not a wire.

Delivery

The plumbing is normally the larger line and is quoted by your own contractor against your room. Free shipping to the lower 48, no minimum, and it stops at the curb — the crate is left at the end of your driveway. Getting it inside is a $600 white-glove upgrade. Getting it inside and assembled is $1,800, which covers everything except electrical work: we recommend you hire a local electrician for that, because the wiring has to meet your local code and pass local inspection. Service fees are non-refundable: if the sauna goes back, the installation does not.
