What basig is referring to is called an edge build up. You don't need to ask for this, it is the standard way to fabricate stone Benchtops. Stone slabs are generally 20mm thick, although the most common. Benchtop is around 40mm as laminate tops are 38mm. You can opt for any thickness you wish with stone as only the edges are joined to give the impression of a thicker top. Caesarstone has 12mm and other products even thiner than that. High end designs are currently utilizing these profiles to provide contemporary lines, however I get the impression you don't want to push any boundaries with your tops. Hope the thickness breakdown helps.

Hi there - exactly the same thing happened to us and I was devastated to see the aluminum strip. like you, this wasn't discussed. So disappointing when you pay so much for a new bathroom. Can you tell me whether you ended up painting over the strips? I'd love to hear what you ended up doing and how it looks, four years on. My sister says she is sure we can paint over them. But I"m so disappointed as it's not the look we were after. We are stuck with our bathroom company who are also doing our bigger downstairs bathroom so at least I can make sure they use white edging around our window. many thanks

Hi Two's Company - Builder says in reference to your picture: "What you are showing is something that could potentially be done. However this is bringing in another work scope item (Hardwood) into your project. A transition piece would need to be made or special ordered (I would assume) and then sanded, stained and finished to match your existing floors. All while redoing floor tiles at the same time." Is this true that it's such a big job? Or is this a piece he can purchase? Also - if we decide to go with a white marble piece - can he follow your drawing for that? I would want to make SURE the marble can be laid flush with the tile and not stick up further. Would there be something on the edge of the tile, before the marble, to make sure there was a small edge? Or would the tile go right up until the marble? Thank you!
