i think hdb by defaults gives standard 2 piece toilet bowl.
taps and shower usually is johnson suisse or american standards depends on projects.
toilet doors by default give bifold laminated doors. not those plastic and aluminium folded doors.
floor they gave vinyl for the whole places except kichen and toilet and store.
but i dun get to choose. all default inside one. only only to decide which one u buay song wanna change only.
Take two piece good, if u wanna do tiles, better spend a bit and do now.
Toilet bowl can be easily replaced at anytime.
Hacking is ******* dirty and messy, those wanna whack one better do immediately.
When you decided to do in the future, resale renovation will be a lot more expensive than BTO.
But tiles is also not say forever, if one day pop, you can't just cement and put back, the height will be different.
Porcelain is about $3+ psf excluding labour.
Tiles that are very non-slip are hard to mop.
Toilet doors are not expensive, i think 600 to 700 can get already.
Remove all the frame make it as wide as possible for future wheel chair access.
Get those aluminium frame with full glass panels. The weight will actually give it more stability.
Glass is easy to clean and good for the kitchen toilet.
Use your intented budget for those atas Grohe, Hansgrohe and spend on these more practical. Showy is really 80-90% Grohe already.
I also don't recommend conceal your toilet pipes. If leak, is almost hack the toilet one.
It will be a total nightmare.
Those with both hot and cold even more jialat, the contraction and expansion of metal may move the connections.
I only have 1 or 2 trusted ID.
Otherwise I bao everything., waste alot of time and really alot of work but quality of course is better and save about 20-30%.
Paint job, better don't save the money, get Nippon professional team, should be the last step.
Those carousell is cannot make it and make it even more problematic in the future.
4 days job can cut to become 4 hours job, really is anyhow.
