With the same internal mechanics and replacement parts as your typical kitchen mixer, much of the same principals apply. One key difference is that this item will be imbedded in your bathroom wall for the next 15-20 years, so it would be best to get a good quality one with good warranty:
· Parts AND labour warranty for 10+ years
· Advisable to get one designed for at least 800Kpa, if not a pressure limiter is highly recommended to keep warranty
· Designed for your wall type (Timber framed or brick)
· Linsol, Caroma, Hans Grohe, Grohe, Abbey,
· Look for a range; Reece Plumbing supplies sell a Sussex "Scala" range which carry good warranty, easy installation and matching tap ware, hooks and rails making your life easier!
· Abbeys Olde English: An older style range of tapware and shower heads that help create a unique theme within a home
