Tavistock Lansdown 400mm Cloakroom Unit with Basin - Linen White Large Image

29th March 2026

The items were delivered on time and in excellent condition. They are for a very small shower room. The room isn't complete yet but the toilet is fitted and works beautifully with a super flush and soft close lid. The sink unit is so cute and I can't wait until the room is complete.
