The size of the pool is 6m x 25m x 1.35m depth.And we have though of going for 48mmx48mm glass mosaic tiles of different color combination. The reason is that we felt that going for a smaller tile might be too much busy on the overall looks and also too many grout lines would be seen. Wheres as the 48x48 tiles would be much relaxed in the pattern and a bit more easier to maintain. What is your take on this? Thank you in advance.

One Follow-up question.. Is there any strength issue with 20mm Granite slab over 40mm Granite.. Are the 20mm granite slab prone to chipping or crack on normal usage.. Usage would be like, chopping vegetables, keeping hot vessels,.. The normal usage what happens in normal indian kitchen.. I just want to be sure that I decide based on experts judgement (like you), as people are just throwing their opinion based on their guess...

Hi Shivam, the best size is either 300mm x 300mm or 600mm x 600mm. The reason is - smaller the tile size better the maintenance of slope to achieve drainage of water. Also, use anti skid tiles to avoid accidents.

8'x10' would be good to go!
