A good quality sheet vinyl floor is going to give you the durability and cleanability you're looking for. It will last forever. There are lots of different choices of colour and pattern and you can probably find a remnant at a good price. You say you need something durable for the wall too? Do you mean the walls in the shower, around your bathtub, or the walls in the rest of the bathroom? A company like Bath Fitter offers an easy care solution which is seamless (for the bathing/showering area) but a good quality paint should be fine for the rest of your walls.

Go for full tiles

We also deals in handmade moroccan cement tiles and you have the option to customise design, size, colours of the tile. Thanks Aakaar Floorings +91 9024200842

Also, I would like more counter space. What size of the sinks should I get? 18 inch? Thank you.
