Bring contractor for viewing, explained to them my requirement and design then wait for them to provide quotation. All design homework had been done 3-4 month prior to taking keys. Once you agreed to the price from a reliable contractor, next is to do shopping for tiles, bathroom fixtures etc.

Do not put lump sum deposit, just pay them by stages. I requested final amount to stay at 20% or else no deal. Some contractor will state final amount 5-10% but when you asked them to finished all final work before releasing payment, they never turn up, rather forfeit this amount if they deem the mess it not worth doing.

If the contractor is financially stable, they will agree to this request. I don't want to engage those that's facing money problem because it's risky.

Tiles and bathroom fixtures from Jalan Ipoh, many shops to choose from.
