Our Story

We started with a question: why do the best wellness experiences happen away from home? The warmth of a hotel hot tub. The quiet of a spa. The feeling that someone has actually thought about the water, the temperature, the way your body rests.

We wanted to bring that feeling home. Not once a year on vacation — every day. So we built a company around it.

Based in Bellevue, Washington, ONSONSPA is a U.S.-registered company. We're young, and we're honest about that. What we have isn't a long legacy — it's a conviction that the place where you unwind and recharge deserves more attention than it usually gets.

What we make

We focus on the products that make the biggest difference to how your home feels — hot tubs, swim spas, saunas, and bathroom fixtures built for everyday use.

Every product is developed factory-direct. No middlemen, no showroom markups. We keep the range focused so we can control quality, keep prices honest, and support you after delivery. Whether it's a compact 2-person hot tub or a full swim spa for the backyard, we design for real American spaces and real daily routines.

What we stand for

Premium Materials

Grade stainless steel, brass and tempered glass. Built to last, not to replace.

Accessible Luxury

Factory-direct pricing. Great design should be within reach, not behind a dealer's desk.

Honest Warranties

Up to 10 years on selected products, backed by U.S.-based support in Bellevue, WA.

Quality That Lasts

Tested for durability, water efficiency and comfort. If it doesn't hold up, we don't ship it.

How we build

We work directly with our manufacturing partners — no brand licensing, no white-label reselling. This means we control the specs, the materials, and the quality standards from start to finish.

Every hot tub, sauna and bathtub goes through stress testing before it ships. And because we ship across the 48 contiguous United States, we coordinate delivery scheduling so your order arrives when you're ready — not when a truck happens to be in the area.

Where we are

Headquartered in Bellevue, Washington — the Pacific Northwest, where water is part of the landscape. We're a U.S.-registered company (ONSONSPA LLC) serving customers nationwide.

2026 — ONSONSPA LLC registered in Bellevue, Washington. Launched our online store with the first collections: hot tubs, swim spas, saunas and bathroom fixtures. Growing home by home, one customer at a time.

We're building this company because the place where you recharge deserves more attention than it usually gets.
Your home, your wellness retreat.
