Change in spec for quote - much change in price?

[fred2]

Recently I asked three different bathroom installers to provide a quote for installing a shower over a bath and adding to the existing half-height tiling so that tiles will now go up to the ceiling.

Only one of them actually provided a quote, but that quote seems reasonable. I have already bought the tiles myself.

After reading the "sticky" perhaps I should instist upon tanking being done also - which I believe is merely painting the plaster with a waterproof coating before the tiles are put on.

In order to try to disguise the join between the old and new tiles, I've just bought some mosiac tiles. I would like a border of a single line of mosiac tiles (about 2.5cm square each, currently stuck to a plastic mesh) to go around between the old and new tiles. The total length of this border would be about four metres.

Does anyone know by how these two changes in spec would change the price please?

Thanks

Depends what your installer charges per hour.

Tank existing walls above a bath should take 1hrs max, plus cost of tanking £35-75 depending what and where you buy it. But it will involve a second visit as the tanking needs 24hrs to dry.

Say another hour and a bit of adhesive/grout for the mosaic border provided the mosaic is a similar thicknes to the tiles.
