It just seems like an odd suggestion to me. Grout isn't expensive in and of itself. The labour to remove the grout is the most expensive part I would think.

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.
