I have a cloak room that has a width of 1035mm that I am wanting to put a combined concealed toilet and vanity in. I was looking at a 550mm concealed toilet and 450 basin. But apparently the 450mm basin vanity of this model is incompatible with the 550mm concealed toilet unit. Has anyone managed to get a vanity basin and concealed toilet unit. In a space with this width 1035mm thank you.
