How much do regrouting tiles cost?

When grout on your bathroom walls and floors becomes cracked or damaged, moisture will seep under the tiles. This can cause water damage, dampness, and then mould, which can ultimately affect the aesthetic of your bathroom. If you want to restore your bathroom tiles to their former glory, then it’s time to regrout!

If your bathroom leaks, the first step is to find out where the leak comes from. Regrouting over mouldy or stained grouting can trap the moisture under new grouting. Once addressed, you can have your walls and floor tiles regrouted. So how much does it cost to regrout tile flooring?

The cost to regrout a bathroom ranges between £185 to £285. Regrouting tile costs in the UK vary depending on the bathroom’s size, as this will determine the amount of grout needed and the labour cost. Grout can be purchased for £17.50 per 12.5 kg bag, and the labour costs around £150 per day.

What are the factors that affect the cost of bathroom regrouting?

How much does it cost to regrout a shower or tiled surface? To calculate bathroom regrouting costs and adequately prepare your budget, take note of the following factors. They will determine precisely how much regrouting bathroom tiles cost.

Type of grout

The average cost to get a shower regrouted heavily depends on the grout type. Grouts with unique properties are more expensive than generic ones. If there is fungal growth in the bathroom, there is an antifungal grout option for you. 

There are also antibacterial grouts, epoxy grouts, pre-mixed grouts, unsanded grouts, and finely sanded grouts. Most grouts start at £17.50 per 12.5 kg bag. Make sure to get the right grout to make the grouting last longer. Hire a Tasker to get the appropriate advice on what grout to pick for your bathroom needs.

Size of area

Naturally, the cost to regrout tiles in a shower area will be higher if your bathroom takes up a bigger space. Larger bathrooms tend to have larger tiled areas that need regrouting. Hence it will require more materials, more time and will incur greater expenses.

Labour costs

Labour costs vary depending on which part of the bathroom needs regrouting. Aside from the £15 to £20 cost per bag of grout, add £150 per day labour fee to regrout tile floor. On the other hand, you will need £185 to regrout the shower tiles. Considering this, it may be more cost-effective to regrout the entire bathroom for an average cost of £250

Current condition of the grout

If the current grouting of your bathroom is already degraded and mouldy, it most likely lets the moisture collect under the tiles. Due to water damage, regrouting may cost more as well.


If you live in major cities like London, regrouting costs tend to get higher. Tradespeople in different areas of the UK charge differently for labour.

Regrouting price tables

To guide you in comparing costs, below is a helpful table to refer to when calculating costs for a regrouting project. Keep in mind that the price of each type of grout will also vary depending on manufacturer, brand, and suggested retail price.

Hiring a professional vs DIY regrouting

Should you hire, or should you DIY? To help you compare the two options, here are the pros and cons of hiring a tradesperson vs doing the regrouting yourself. 

Hiring a Tasker

DIY regrouting


  • Learning to regrout properly takes years of experience.

  • Old grouting can be removed properly with the proper tools and proper techniques.

Can cost less since you would not need to pay for labour costs.


Can be more costly than DIY

  • If not done carefully, moisture can leak under the tiles, which will cause water damage and mould.

  • You will need to buy extra tools and safety equipment such as goggles.

  • If not used to the job, it can be very challenging to achieve a smooth, quality finish.

The regrouting process

To give you an idea of what the job entails, here is an overview of the process. This will also allow you to evaluate if you can do the regrouting job by yourself or if you need to hire a professional to do it. 

Check if there are leaks

If there are brown moulds, this can mean that water is getting behind wall tiles, under the floor tiles, and soaking through the joints. Make sure to find where the leak is coming from and have it fixed first before regrouting. Otherwise, there is no point to regrout as you will still encounter the same issues.

Remove the old grout

An ideal tool to remove old grout is a drill, which will let you work through the surface of the grout and under without damaging the tiles. Don’t forget to wear safety goggles to protect your eyes from debris! Once finished, go over the lines using a screwdriver, then vacuum the debris to make sure you have removed any last traces.

Be careful in removing old grout, as chipping or cracking bathroom tiles can cause increased work time, additional costs, and stress since it can be challenging to find the exact tiles to match.

Mix the grout, then apply

There are ready-mix grouts available in the market. However, if the grout on hand needs to be mixed first, you will need a tool called a grout float (which helps you mix the grout) and a scraper (to get rid of any excess). 

Get rid of the excess

Clean off any excess as you go along because they tend to dry quickly and can be harder to remove once set. Use a damp sponge to remove them, then leave the grout to dry.

If a tile is damaged

If a tile is damaged while removing old grout, use a chisel to remove the broken tile. Get the new tile and apply the adhesive on its back part. Position it using spacers to maintain proper grout gaps. Once dry, remove the spacers and grout the joints.

Save time and make sure that your regrouting project is done correctly. To get an accurate quote for regrouting, put up a task now and talk to a specialist about your regrouting requirements.

Can I grout over old, damaged grout?

It’s possible to grout over old, damaged grout. However, you won’t address the moisture issues that could be trapped under the tiles. So to prevent this and achieve a smooth finish simultaneously, have the old grout removed first.

How long does a regrouting job take?

For planning considerations, allot one to two days for regrouting jobs regardless of the bathroom size. The exact time will depend on the speed of your tradesperson.

Can I grout immediately after laying new tiles?

No, you need to wait 24 to 48 hours before grouting new tiles to ensure that they are properly set.

How long does it take for grout to dry?

Set the grout to dry at least overnight for a total of 24 hours. Then wait for a few days or up to a week to ensure that the moisture took its time to dry up.

Can I paint tile grout?

Yes, you can! But choose a paint that’s grout-friendly. Epoxy colourants or epoxy paints come in various colours and would work well on grout.

Do I need to use grout joints?

Yes, this is highly important for gaps! Gaps between tiles are necessary to allow for the expansion that happens when there is a temperature change. Besides that, they stop moisture from reaching the substrate, preventing water damage behind tiles. Use 2 mm joints for a wall tiling project and 5mm when using natural stone.
