What do you do with a broken shower controller, no shut of valve (except to the whole house!), no access panel and old tile in the way? We had this emergency, and called Tim’s Quality Plumbing (I’d seen their work at a client’s home). Mark M was awesome and reassuring, and got it all fixed, (except for tile replacement of course). It is never fun to be in this situation, but he made it go as well as possible.
