Do-it-yourself is fantastic, and am passionate about it. Since you’re combining two distinct materials, caulk should be used at the joint between the flooring and also the tub.

Grout is not very flexible; therefore, it is not really the preferred material for the purpose, whereas caulk allows for mobility while simultaneously acting as a sealant. Grout, on the other hand, can crack as a house settles.

Should you Caulk a Tub Surround?

Water cannot seep out via the underlying grout seam if the tub link is caulked, and moisture accumulates up, feeding the mold that finally grows.

Therefore, if you have had a ceramic tub surround, maintain the grout in good shape but just don’t caulk the joint, and indeed the compartment will perform substantially better.

Is it better to Caulk or Grout shower Corners?

Owing to tile deformation, the grout in bathtub edges will fracture and slip out. In bathtub corners, caulk creates a waterproof, flexible barrier. Apply caulk in bathroom borders and anywhere else at which tile touches an adjacent surface.

Can you caulk over grout around the tub?

Caulking over grout isn’t a good idea in general. Re-grouting is your top choice if you’re looking to replace the grout linking the bathtub to the surface or covering the area between adjacent tiles or stonework.

What is the difference between grout and caulk?

Caulk is composed of flexible resins such as silicone or polyurethane that allow it to accommodate motion.

Grout, on the other hand, is created by combining water, cement, and sand. Those compounds aren’t as pliable as caulk, therefore harden.

Grout can withstand water, but it is not impermeable. The best approach to grout’s progress, particularly tile grout, is that it must be completely submerged for an extended period before it becomes susceptible to letting water through.

How often should you re-caulk a Bathtub?

Within a year, the region around the bathtub in a custom-built home may have to be recaulked attributable to typical settling. The caulk surrounding your tub, on the other hand, should typically last at least five years.


Grout and caulk are basically two distinct materials. If you reside in an older building with an antique bathroom, you can conduct a renovation or reinstall a bathtub. Do you recognize when grout or caulk should be used on your tub?

Grout prevents water out of floors and walls while also making them look brighter. Grout needs a fissure to “grab onto” and can prevent cracking at tile edges.

Because grout does not include latex, it is susceptible to cracking when subjected to motion. Grout can get stained and unclean after decades of use.

Caulk, on the other hand, is watertight and bendable. Caulk is strong and malleable enough just to bond two kinds of materials, connectors, and edges to block air and water leaks.

Caulk can be used in a variety of ways around the house, notably around the bathtub. Caulk can be used to protect drains, pipes, bathtubs, and bathroom fixtures from water damage, as well as to weatherproof doors and windows.

When organizing a home improvement project or simply performing routine maintenance surrounding your bathtub, it’s crucial to understand the differences between grout and caulk, as well as the appropriate applications for each.

We’ll look at whether you would prefer caulk to grout, and what if you detect a crack between your bath tile and the tub

Can I Caulk Over Grout?

The ability to apply caulk over grouted sections is a common topic among homeowners. Whenever your tiles meet your tub, caulk is normally put all around the periphery.

You’ll most likely use caulk in spots where there’s also grout in those circumstances. A technician, on the other hand, would not suggest caulking over damaged grout to seal it.

The possible explanation you shouldn’t use caulk to repair grout is because you can unintentionally create the ideal breeding habitat for fungus.

Your caulk may shrink and dry up over time, causing it to lose its capacity to form a solid seal. Mould can get under the caulk and begin to develop if the substance is weakened in this way.

Mould can creep beneath your walls or through your basement if left uncontrolled. You’ll have a far larger concern than simply eliminating caulk or grout whenever such happens.

Scrape and replace the current caulk surrounding your tub if it appears to be aging or mold is forming. When caulk curls up in the edges or turns brown, it’s time to replace it.


Finally, unless you are unsure whether you have perpendicular troweling, do not even reroute the foot of your wall; instead, re-seal the grout inside the whole of your wall with a grout sealer, then put silicone caulk around the entire base of your bathtub.

Approximately once a year, strip and replace the caulking.
