Thermasol, after you get past the initial price shock has a LIFETIME warranty. They are the leading American Steam Generator by most Plumbers. Their product is built heavy duty and they offer units for both Residential an Commercial operations. For Plumbers its the unit with the least amount of callbacks when installed properly. Have heard good comments about Mr. Steam for residential applications as well.However their warranty is not lifetime. JMHO.

I don't understand the last post to this thread? Thermasol offers a 5-year replacement warranty on all their controllers. Why would you pay to replace it? Maybe you had it more than 5 years? If so, then it's too bad it failed but how long do you expect it to last? I doubt you could expect a car to last reliably with no problems longer than 5 years, so why expect that of your steam shower. I have a PRO-395 that I installed 14 months ago. It just failed tonight. Not sure if it is the controller board or the heating element, but it stopped producing steam. Called tech support and they are shipping me a new replacement unit tomorrow and paying for the install, all at no cost. I am going to call them tomorrow to talk to them about the fact that it failed so soon. They are supposedly the best and charge a premium for their product. I am curious how they will explain that it failed so soon. Will update this post if they say anything interesting. Update: Spoke to them this morning and they are sending me a new unit, and pay for installation charge. One other thing. Someone in the tread above talked about making their shower with a 10 ft ceiling. Don't do that! That is just dumb, and will affect the experience of a good steam. If you ever want to make your steam shower bigger, do it in the length or width but never in the height. My house has 10 ft. ceilings, but my shower has a 7.5 ft up to an 8 ft. ceiling and that is plenty high enough. The 7.5 ft part is over the bench so the fact that it is lower there makes no difference because you are sitting down.

We have a Kohler steam generator in our basement, about 12' horizontally from the steam head in the shower. Its a good idea to periodically flush the steam generator as minerals can build up in them (the steam is pure water, the minerals remain behind.) The drain fitting on ours is plumbed with a ball valve to our sump pump so the steam generator can be periodically flushed. If it were in the attic, my guess is that the generator would rarely get flushed, if ever. I would opt for a nearby closet. There is a bit of rumbling on start-up as the supply line fills with steam but during operation it produces a constant low-level whoosh sound. Insulation on the lines helps the noise as well as reduces heat loss, the steam temp being 212F is above the temp rating of the box store pipe insulation. Pre-shaped high-temp fiberglass pipe insulation can be purchased from sources on-line.

We are looking for an experienced installed who can install Kohler DTV+ shower and Mr. Steam iDream steam package in the shower.
