You might like to ask someone to help you carry this up the stairs, but it's easy to assemble once it's been unpacked. The Delta Bathmaster is a lovely piece of kit. There's no need to drill into your bath or make any permanent fixings. It's compact, lightweight and it fits virtually any bath. (Some people find it helpful to keep a bath step next to the bath to mak eit easier to get into the Bathmaster.) It lowers to 2.5 inches and it reclines to 40 degrees (all by remote control!) for a truly natural and luxurious bath. All this together with a super fast one hour charging time.
