- Drain system
There are two basic approaches to the ofuro drain design:
1) Without overflow. Traditional ofuros simply have a floor drain and no overflow system. This allows the tub to fill to maximum depth, right to the rim, and potentially overspill. This means that the floor under the tub must be waterproof and have a drain to handle overspill.
Good options for a floor drain are trench drains, trough drains, indirect drains or channel drains.
The ofuro drain is shown in the photos below. The size is 1.5" NPT (standard pipe thread), and the closure is a swivel top with o-ring. Finish choices available.
2) With overflow. If the traditional method above is not practical for your design, choose either to add a Remote Tub Drain and Overflow or opt for the optional Standard Overflow Drain to achieve a system that prevents the tub from overspilling.
Both are external fixtures which limit the water level in the tub and allows the Ofuro Tubs to be installed without the need for a draining floor area.
