Insulated tank toilet w/14 in rough in
My house is quirky, and my only bathroom is quite small. I'm planning to replace my Homart toilet, which seems to be original to the house, because it gathers so much condensation in the summer that it's rotted the plywood subfloor. Our mixing valve can't handle extreme heat and humidity, so now we're going to try an insulated tank.
I was set to order a Toto Drake (round seat) until I realized I have a 15" rough in. From the discussions here, I understand I could theoretically use that model anyway; however, it would leave no leg room.
From my research, none of the Toto toilets is available with both 14" unifit AND an insulated tank. Is that so? If that's the case, would you please suggest the best alternative solution?
So far, it seems my choices are to re-rough in the plumbing, which sounds expensive, or to go with the Gerber Avalanche, which seems unpopular. What say you?
Thanks for your thoughts on the matter.
