You buy the tiles or they provide everything. If they do, what tile they are using? Local or China made and how much per square feet? That should be considered too. Tile prices vary a lot.

I see. I'm not in KL but I still think that is expensive. Wait what others say about this.

Depends on the cement type use. For normal cement, you can probably walk on it after 3 hours. The contractor will say after 1 day. I would wait for 2 days. The cement will fully cure in 7 days if not mistaken. I parked my car after 2 days though and no problem

Have no idea about grade, but the question is if the grade the same international standard? WHo grade the tiles?

You should ask for more detail. If it is just remove and put new tile, it is expensive. For that price probably can lay BRC wire mesh to reinforce the strength, I guess.

Don't just look at the price. Some China one is cheap and looks good too. I've seen tiles used in bathroom become stained as it is not cleaned properly. However, the darker spot cannot be brushed out. It looked like the tile absorb the stain from below and appeared on the surface. This will never go out

Maybe some others has experience this and have knowledge how to choose a good one.

In olden days, normal cement was used, unlike today where there are cement for different purpose. My bathroom just apply adhesive and put tiles directly on other tiles because I just want to prevent water flow from shower area to sink area. It is just a tile thickness only. It has been more than 10 years and still no problem

Different tile manufacturers have their own technique. In olden days tiles absorbed water more (more porous). Wall tiles are even more porous. That is why they soaked tiles for like 15 minutes before drip dry them. Otherwise, the tiles will absorb the water from cement too much and too quick thus will not stick properly. Nowadays, there are tiles that need no soaking at all (as advertised) and will adhere securely to flooring.

Tile on living hall wall?

I was imagining bathroom since in Malaysia, I think it is rare

For feature wall many tile style can be used. I think you can just Google wall tiles.

As for the tiler in your area, I think the tile shops/supplier normally have tiler contacts since many contractors would usually leave their cards at the shop in case people ask. Why not try to ask them wen visiting their shops for ideas.

If I were you, I would not go for tiles. I'd go for vinyl wall paper with a big scenery. My office wall got a forest picture from floor to ceiling on one wall. Very cooling

Got several sceneries but here two of them. One is Might Sky and one is just Forest

Yes the Forest one got light on side and it looks like refreshing morning sunrise

Googled told me that Porcelanosa is Italian tile manufacturer.

I think any tile from known manufacturers is as good as the others. Even each one also has different price according to series. You have to compare specification if you are looking for anything specific.

Google was correct but my brain malfunctioned

I think there are good China made and there are also poor one. I saw some some using China one the tile absorbed dirty water from underneath and surfaced as dark patches on tile surface. The only solution is to replace the whole tiles

Yes printing is another matter. My office renovated with lovely wood-like rectangular tile. Just over a year the print has faded The different is the tile meant for public place and for home. Price is different too.

I think it is best to ask the shop that sell the tile and what kind of warranty offered by manufacturer.

Actually I want to say when asking for warranty is to test how confidence the shop that sell the China tile. Usually when shop sell China one, the warranty void once you pay them

There are grout meant to be specific for wet area like bathroom instead of just normal cement base. It will not stain like my bathroom (by developer).

I am thinking of scraping it and use silicon (commonly referred as caulk).

Grout will crack if there is pressure applied to its contact surface but easy to apply. Silicone is flexible but harder to apple like pro. Need a bit of practice

Your choice

Why you want to do that since it is already tiled? Any difference? You want something new?

Yes possible. There are many brand and I don;t have name. You can just go to tile/hardware shop and ask. They can recommend.

Existing tile just need to clean from any oil or grease. Just follow the adhesive instruction.

Putting space will make it look more professional with uniform spacing. Some just use match stick. No need to buy those plastic spacer.

As for the existing socket, remove it and you just need to drill hole to pass through wire. Socket can just crew over the tile. No need precise cutting whatever.

No need to hack. My bathroom floor also put tile directly on top of existing tiles. I want to create different level (just a single tile thickness) to separate wet and dry area by preventing water from shower to overflow to sink area. I just put simple curtain to prevent water splash.

It is more than 10 years already and still fine.

Most shops that sell tiles have some excess but the main problem is to find the same tile unless yours is plain white.
