Updating your bathroom designs involves more than just deciding what colour bath to pick! A re-design means that you can swap the layout and make room for a separate shower and more storage units. If you're sticking with the same layout, make sure you measure your bathroom suite carefully before you go shopping for a replacement so that you know the new items will fit. Re-plumbing and re-wiring will push the cost up so stick with the existing service points if at all possible although this may not be unavoided if you want to change the positioning of the bathroom suite.
