FAQ's - equipment


Q #06		 I would like my bath tub equipped with a circulating pump.
A #06 Sorry, we cannot supply from Japan heating / filtering / circulation pumps or whirpool systems. Maintenance or replacement of parts would be too troublesome and expensive. You should find one locally and send us the pump specs so we can modify the bath-tub as required. Please note anyway that in most cases a pump is uneconomical and unpratical for private use.
Q #07 Do we need to adapt the diameter/length of the fittings? We are planning to use a circulation pump.
A #07 You have to think of the hinoki tub as a large basinet. It is simply set on the floor and not connected with any piping (a part for the case of a pump). The faucet is wall mounted and the water flows into the tub. Often the drain is not even connected with any fitting: the water flows out from the bottom towards a floor-drain.
For the pump fittings: you can let us know the exact location of the outlet and inlet so we can prepare the openings. Actually, opening the drain hole (of the right size, in the right location) on site is the probably best option as the tub is made of solid wood and opening the hole is very easy. We do not have availability of fittings with diameter/threading matching the connections of your pump. You should request the pump manufacturer fittings at least 3" long. (the tub wall is 42mm thick). In the worst case, you should be able to have fittings custom made in your country without too much fuss.
Q #08 Your site recommends 'pure warm water' Is a high salt content okay? My image is the salt pools I sat in at Spa LaQua. I am thinking of Israel Dead Sea Salts, or another healthy salt.
A #08 There isn`t any direct problem about using salty water in a hinoki bath as long as: 1) once tub is emptied, it should be generously washed with normal water to avoid oxidation and staining 2) we will use stainless screws and plates, so no problem.
Anyway we do not have experience of this and do not know what it will happen in the long span. It may be OK, I do not know. You would have to try at your risk. I feel that salty water would at least alter the aroma and therapeutical properties of hinoki, but this might be just a prejudice.
Q #09 Do you only make ofuro, or do you also provide disinfection systems, recirculation pumps, and everything I need for a commercial ofuro?
A #09 To be honest, building a tub is more similar to naval carpentry than a normal plumber job. We do not supply any machine or pump equipment of any sort.
I recommend to find locally a pump and cartridge filter. If you replace the water every 3 days or so, you might skip the filter. About the disinfection: do not use chlorine.
Ozone seems to be popular, personally I would recommend a salt chlorinator. Please ask a pool equipment dealer near you. I had a client who used 'Aquapure' in a small pool and was very satisfied. It is a product available in the US. See: http://www.jandy.com/html/products/chlorinegenerators/aquapure_faqs.php
