Does anyone have any knowledge of ReBath or a similar company and their reputation? I know it's not DIY but could use some feedback. I want to replace my existing tub with a shower in the same or similar footprint. My husband is disabled and has difficulty getting in and out of the tub shower. I am financially challenged and have only one bath so can't go for weeks without being able to use it during construction. Not to mention that as far as I can tell the tub is original to the 1940 built home.
