I would still suggest tanking/waterproofing the room prior to the installation of a standard shower tray or bath. Waterproofing membranes with the European Technical Approval will withstand normal movement within a house but the flooring and walls need to be of sound construction - a wetroom can be properly fitted in age of building. These principles apply to a standard tray or bath as the silicone beading around the edge may fail (from movement/age) and let wall bypass the tray, causing damage to the building underneath. This picture was taking after a bath with wall mounted shower was removed. The silicone had failed causing the wood to rot. This was all replaced and the below was created in its place: A bath will be easier for people with young children and if you plan to sell on, a wetroom will appeal to some where a bath will appeal more to others. Which ever path you choose (both your designs look nice) I would recommend waterproofing the room before it is installed. Kind Regards Mike

I love the warmth of the wood vanity with the 2nd design. Although marble is a design classic i just think the 2nd may possibly have more longevity as there’s nothing to go off of? I really like your feature tiles but they’re pretty on trend, where are they going? i’d just consider if they can easily be changed when trends/taste change. I only say that as my kitchen tiles make quite a statement but they're restricted to around the oven and were relatively cheap

Thanks both, I did think about putting in a tall unit to the right of the window but the client wanted a worktop going all the way along. Yes there will be some storage under the basin but it is only a 600. I also played with putting a unit opposite the WC but you end up with 400mm between the end of the WC and the unit which is no good. What do you think to this? Putting open units on this wall here.

Your layout seems very well thought out. Here are a few practical things to consider. Choose a bath with a non slip base safe for standing when showering but is also comfortable to lie on. Install a dual shower head system with a longer than average hose which makes children’s hair washing easier and helpful when cleaning the bath. As Isla says, a pivot screen is essential to make it easier to bathe children but also to reach the bath taps. A bath with wide ledges which can hold containers for toiletries, sponges, toys and so on is also handy. As is a sink unit wide enough for hand-soap, toothbrush holders, etc. Having a large sliding door mirrored wall unit above the sink (not the toilet!) is also great for keeping your surfaces clear. I would always choose wall panels instead of tiles as they’re much easier to keep clean.
