Yes if the tiles are not cracked and are in usable condition. You can also choose to leave minimum gap between two tiles.

Can anyone please suggest a company name, I am looking for gold color tiles for my swimming pool in Delhi ?

Hello there, You could scoop them out with a flat trowel and scrap cement backing with that as well. But it won't be much of a success and you will lose around 30-40 %. You could DIY broken tiles mosaics as an art ; frame and fix it on the wall itself with an appropriate glue. Or search for other DIYs on youtube. You could replace them with decals as described @cornerstone studio , but there's a catch ; high heat areas could deform and de-glue the decals as well. There are many projects possible with broken tile mosaic. Just search and follow an easy one. Regards, Aurum Ideas and Spaces Bhubaneswar
