Am I in the wrong

If he’s only done 1.5 square meter in that time you want another tiler

Should abide by original quote and wait suggested amount of time for adhesive to dry if grout too soon can lead to cracking

If the work was agreed as a total price then it's only him who is losing out by taking so long to do it. On a project like this you should just get quotes for labour only and you should just provide everything the guy needs, that way there's no issues. And I personally would never grout straight after laying the tiles but depending on what product he is using then I don't see why he wouldn't be able to.

. Tiling metro tiles around a window does take time ..
. A standard bathrolm fully metro tiled should take between 5 to 6 days
. Always get a price to do the total job .not a day rate
. Adhesives . Thdebetter option is powdered adhesives .. better grab and better setting qualities

First, the agreement must be implemented
The tiles must be left to dry
If the tiles are not completely dry, they will fall out of place

The price is the price if he agreed a price with you for the whole job then he should honour that. Any extras that he has supplied ie adhesive or grout ect should be confirmed with you prior to purchase.

1.5 sq meters in 6 hours is a bit odd indeed. About tiling to dry.. probably he used the wrong materials, usually you can install and grout the tiles in the same day.

Hello from Mazzy’s builders . Tiling for a experienced tiler should be straight forward . Yes tiling around a windows is one of the most complicated parts but shouldn’t take too long . And as for the grouting I do not recommend grouting on the same day if it normal tiling adhesive but if it is the rapid set tile adhesive which dries in 2/3 hours then it is possible to grout on the same day

Some times going with the cheaper trade is not a good option and is good some times to insist because you sre paying not him so you have to insist for the job to be done correctly .. and you need to make some conversations clear from the beginning if i am asking for X amount tha it not extra charge

If its a quote you have to stand by the quote unless it's major job to change it like if the plaster has to come off and re plasterboard out

Your are not wrong. you are not ment to grout the same day unless you use a rapid adhesive and give the recommended drying time. the tiler has gave you a price for job completion so if it takes longer than expected his quote was not the best to start with some areas do take longer than others but that was ment to be assessed before quote was given

From my point of view, I only paid them for the tiles installed, maybe something extra for the road and I install the rest. I usually only use quick glue (uncared in 3 hours).

Before being able to answer I have few questions.
Does the tiller buy the materials or suggest it to you?
Why you consider tricky or what you mean by tricky around the window?
I will give you an answer about the grout. Basically even if the tilles adesive is quick dry I suggest that at least 24h should be given to dry before grouting usually we give 48h because the tiles could move out of the place and you could develop mould behind the wall because it remains wet.

You grout after the adhesive is dried to prevent the tiles from moving, with price work you need to see all the cards that are being dealt in order to move forward accordingly

You got to go with manufacturer’s instructions if drying is 7 days then grout on the 8th

Prices are agreed before starting any work this will include any extras or discussed prior to work. Tiling can be grouted the same day it really depends on the adhesive and substrate tiling on! 6 hours around a so down seems to be a little too long to be fair but this even if it takes that long will fall into his price!

Tiler in the wrong agreed a price doesn’t matter how long or how quick it takes as long has within an agreed time

It sounds like you're dealing with some concerning issues with the tiler, and it's understandable that you want the work done properly and as agreed upon. Here are a few thoughts and suggestions:

Communication is Key:

Clearly communicate your expectations and concerns with the tiler. Make sure you both are on the same page regarding the scope of work, the timeline, and any additional costs.
Reiterate what was agreed upon in your initial email list, emphasizing that it was a comprehensive agreement.
Timeframe Realism:

It's important to be realistic about the time needed for the work. Tiling can be a meticulous process, especially around tricky areas like windows. Ensure that the tiler understands the importance of allowing proper drying time before grouting.
Grouting Timing:

Stick to your decision about not grouting on the same day. Explain that it's for the longevity and quality of the work. Quick drying adhesives still need adequate curing time.
Additional Costs:

Discuss any additional costs that have been proposed by the tiler. If you have a written agreement or email confirmation, use that as reference to avoid any discrepancies.
Quality Over Speed:

It's crucial that the work is done properly, even if it takes a bit longer. Rushing the process can lead to mistakes and a poor-quality finish, which may cost more to rectify later.
Review the Contract:

If you have a written contract, review it thoroughly to ensure all aspects of the job are covered. If not, try to create a written agreement or confirmation of the scope of work and terms.
Seek Professional Advice:

If the situation escalates and you're unable to come to an agreement, you may want to seek advice from a professional, such as a construction consultant or legal expert, to understand your rights and options.
Remember, it's essential to have open and honest communication with the tiler to find a resolution that works for both parties. If he agreed to a certain price and scope of work, he should honor that agreement. If there are legitimate additional costs, they should be discussed and agreed upon transparently.

You can usually grout a few hours later with most adhesive. As it doesn’t necessarily have to be bone dry to grout it

My advice is to get a quote in writing or by email including the extent of works and the total price including any materials supplied by the trade. In this case however your within your rights to only pay the quoted price but by the tone of your text it sounds like the chap might not return, in which case you would have difficulty find someone to complete the work. Unfortunate situation

So...
The primed surface can be tiled after 24 hours.
7m2 walls bathroom- one day of work.
Cost £570 including tax and materials.
Thank you.

Tell him not to carry on if he ant sticking to his Agreement

A good background on your situation but not enough for a tiler to comment. We always grout 24 hrs after tiling, but it depends on your substrate. Tubs are rarely used unless solo on herringbone above counters. As regards demanding additional monies I would stick to your guns if its included in their quote. The fear of course is losing the trade.

if the tiler wanted to complete the job within the time scale given he should of used rapid set. also he should of fully explained to the client the process.
The tier and the client should of came to an agreement first of all before the installation process started and both fully aware of any added cost' terms and conditions.
