Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

Our job does not end when your order ships. We stay available through installation and beyond. If something needs attention, we stay involved, work the problem, and help see it through.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Sauna and heater customers also receive free shipping on sauna accessories for life.

Planning a sauna, or need help with one you purchased from us? Our founders have built saunas from the crate up and both run saunas at home. New customers and existing Sauna Marketplace sauna and heater owners can Open the 3D planner.

Custom DIY Sauna Package

Plan your sauna

Set the room size, explore benches and wood, and review your sauna here.

You bring the framed, insulated room. We work out the cladding, bench material, radiant barrier, vents, and small pieces that turn it into a sauna. Configure the room below and choose Invoice Me at checkout so we can review the dimensions, available material, and timeline with you before the package is finalized. A bucket, ladle, headrest, thermometer, hygrometer, samples, and project support are part of the process.
