Do you need a water line?

No, you can just fill the tub with a garden hose.  You are of course welcome to run a water line if you prefer though.  Just please be sure there is a back flow prevention valve on there so that hot tub water cannot back up in your household water supply.

Do you have 110v systems?

Yes, we can technically run gas heaters off of 110v.  Trust us though, you do not want to.  You are better off on a 240v system and you would need to hire an electrician to run a dedicated line regardless of the voltage.

Can they be outfitted with jets?

Absolutely! Just like a normal hot tub or spa an Ofuro can be jetted.

Also, keep in mind that jets require plumbing on the exterior of the Ofuro. It will almost certainly be preferred to cover/hide this plumbing with some type of deck or surround, build on site.

How are Ofuros heated?

Most residential home do not have enough hot water supply to fill an Ofuro. With every cubic foot of water being 7 gallons, smaller Ofuros hold about 100 gallons and a “typical” 5′ x 3′ x 26″ deep Ofuro holds about 160 gallons.

Some instantaneous water heaters can fill an Ofuro, but most people chose to add a small recirculation (pump) system with an electric “spa” heater. Adding a filter and ionizer to this, one can reuse the water for up to a week without the use of standard hot tub chemicals. Using a small amount of chemicals the water can last up to 3 months.

What different woods can an Ofuro be made of?

The vast majority of Ofuros are made either of port orford cedar or teak. Other woods that have been used are yellow cedar, western red cedar. While port orford cedar is more traditionally Japanese, teak is slightly more durable and less prone to staining. Due to the majority of the production costs being labor, the type of wood you choose has little effect on the overall cost of the Ofuro.

How do they drain and overflow?

In order to obtain maximum water depth for the most enjoyable soaking, Ofuros don’t have an overflow like the typical American bathtub. While we have on occasion installed “conventional” overflows, the preferred style allows the Ofuro to simply overflow over the top. This of course requires that the Ofuro be installed on waterproofed floor with a center drain.

For draining there’s a few options. If the Ofuro is being filled and drained for each use, the location of the drain can be specified to exactly match your plumbing layout.

Ofuros with a recirculating heating system or that are fully jetted, can have the above configuration as an option, but more frequently the draining is done through the plumbing. A “T” with a valve is simply installed into the added plumbing.
