Actually depent on how much area you need to repair, but from my experiance, i don think is cost too much, because what you need to do is, do a litter bit hacking on the crack area, let that area have enough space to put plaster in evenly, then just paint it back will do. But will the problem come back again? Then is depent what cause the problem, is that your stuckture is moving? or just a normal cracking.

Actually, construct a stucture with roof tile are much more cheaper compare by slab.

I guess you should ready at lease 20k for that.

Base on your simple calculation, Tile cost RM7.5/pcs, actually normally we will count abut wastage too, so have to add in about 5% ~ 10% of tile wastage, so make it round to RM5000, and the rest of the price will be a labour of worker, cement, sand and other material, actually is a bit high, you can ask for a discount from the price.

Doing renovation on bathroom specially condo, is a very costly job, which not only related to how much u hack and how much u lay. Is also u have to remove all the bathroom accessories & fitting, and re-install, water proofing for bathroom (which have to be done), and most of the time removing tile will effected water piping, so have to re-touch up on piping. so, there is a lot of cost to include. so, that depent on site but cant counting by sf.

Is your table included any leg? or wall to wall? because the length of table have to count included the leg as well.

Is the price included tiles? even not, is already a very good price, don think, and just go for it.

Ya, is almost about the same price, is just normally hacking marble usually will be a bit more expensive. and the price usually included cement and sand as well, so if you say RM8.5 not include tiles, is about that already i think.

and dont forget your calculation is base on 0% wastage. and that i think never happen b4, so you need to at leave add in 5% for small tile and 10% for bigger tile like 1' x 2' or 2' x 2'.

why not? it must be done

In this case, have to check your site then only know, because have to see do you have beam or column around, and see where can get the support and so on many thing.

is very cheap only, should not more then RM20 i guess

Moving a toilet? then u need to ready at lease 8k to 10k.

May be can use polycarbonate, cost may lower, but is still depent on site.
