It depends on what you order.
They have some complete shower cubicle sets in composite stone which
are produced from a choice of a few different patterns and the size can
be varied. The set consisted of base and large format wall tiles for
three walls in the same material - i.e. meant to go in an alcove.
There were a few of these in their showroom at prices in the £1200-1800
A stone base (only the base) was in the same price range depending on
the material, granite being at the higher end because of it taking
longer to machine. Apparently main cost is machine use time, with
second cost being material. The composites are less because they
machine quickly and easily in comparison, although softer stones were
not much more than composites. Equally, one could select a
particularly expensive granite and not get much change from £3k.
The firm does subcontract work for major projects and also supplies
shaped stone to order.
I went to them for two pieces of 20mm granite for my cloakroom project.
One, which is a cover.shelf for the cistern at one end of the room
was almost rectangular but not quite - the room is very slightly
trapezoidal at the end. The other is an odd shape used along part of
one wall as a shelf/vanity top. Over part of its length it is fairly
narrow and widens for a rectangular top mounting basin at the end. I
templated these in 6mm MDF and selected the material and a honed rather
than polished finish. Both pieces fitted precisely and look
excellent. The supplier had the pieces available when they said they
would as well, so I can recommend them.
