Allure flooring against bathtub

I am thinking about putting Allure in my bathroom, right now it has a sheet of linoleum and caulking against the bathtub.  I am not sure whether to remove the linoleum or go over it when I install Allure, I'm also trying to figure out how to run Allure to the bathub, do I need to caulk it, use a quarter round, how do I seal it to prevent water from getting into the subfloor?

Hey cak165,


You are right on the money when it comes to using Allure in your bathroom. I am a flooring specialist at my store here in Atlanta and it really is an easy product for rooms where water is a constant issue hitting the floor on a daily basis.


cak165, you basically are speaking of the exact steps I would recommend for your Allure against the bathtub. In terms of what caulk and quarter round to use, I will go into a bit more detail with you, so the trim will stay put and you'll be preventing any water from coming underneath. In the image below, you will see how the "giant" quarter round is placed as well as how the adhesive is placed underneath the trim touching the Allure flooring. I made the quarter round bigger in the diagram just to show you more detail in the image. Below the pic I will talk about and show the exact type of adhesive to use underneath the quarter round.


alluretub.JPGBefore placing the quarter round, simply install the Allure flooring up to 1/4" from the tub wall. This allows the floor to 'breathe' and float properly. Next, install the quarter round down using a silicone based heavy-duty adhesive (not sealant, which is a caulk). A specific adhesive we use that works great in wet locations is shown in the picture below. I can't say enough of this glue, I personally use it on all projects if I need a clear and strong hold.

This is the best nail-free solution I have found to get a water-tight floor, especially near the edge of your tub where it meets the floor.


Hope this has been helpful, and please let us know if you have any further questions.

Thank you for the illustration and explanation, you're way above average in my book Joe!  Home Depot should be glad to have you answering these questions...  ;-)

Great information - thank you! Question: How would you address a situation where you have a bathtub with slightly curved ends? Can't use quarter round very well in this situation.

Hello RamJacCorp,


Thanks for your great Allure question, and welcome to the community!


There are several ways you can get a solution for a curved area, such as around your bathtub. My last apartment had that older curved style, so I know exactly what you talking about.


And you correct in saying that a regular quarter round wouldn't serve you well in this type of situation, but there are other options available.


For example, one that is a special order item by Flexgrain. These kinds of mouldings follows any curves or indiscretions on the surface that it is being installed upon. The smaller versions can be installed in a bathroom, and look great as a finalized piece.


I realize these maybe more expensive than other products out there, but it eliminates any excessive cuts.


However, you can use a vinyl trim in our flooring department by either Schluter or M-D, depending on your tastes and how curved the edge is.


Just as important, you'll need to make sure you install the Allure planks are curved as well. You can achieve this by using a contour gauge to get the perfect snug fit for the flooring where it meets the curved tub.


Did you have your color or style picked out in Allure? Or was it Allure Ultra? Let us know if you have any further questions, and we hope to hear from you soon!

Why not just run the allure parallel along the tub line, skip the 1/4 round and then use GE silicone caulk to seal the allure to the tub edge? 


Also, if a 1/4 round must be used as indicated and glued down using adhesive, one thing I was unclear on was whether you are gluing the 1/4 round to the allure or to the tub edge?  Or both?  Thanks Joe

Hey Durango,


Thanks for joining us here on the community!


No matter if you lay the Allure planks parallel or congruent to it, placing some form of floor moulding such as quarter round is crucial to the installation. You have to remember that this is a floating floor system requires a trim to hold it into place.


Failure to do this may not lead to the install being jeopardized, but it can allow water to reach under the planks, leading to subfloor damage.


Afterwards, you can use GE silicone caulk to seal it and prevent water from getting underneath the planks. NEVER glue or fasten the moulding to the planks, only do it to the vertical surface (wall, tub).


You can use a construction grade adhesive to stick the trim to the tub surface. All other areas of the moulding like your walls can be fastened with finishing nails.


Any additional questions you have regarding your new floors, let us know.

Hi Joseph

Can you clarify the part of using adhesive on the quarter round on the flooring. It seems in your first post with the picture you say to use adhesive to fasten it to the flooring, but in your last post you say to never fasten moulding to the planks?

Hey again blott10,


That's right; never use fasteners (screws, nails) to install moulding into the floor. Only use these for going into the wall.


Using adhesive is different, since you aren't puncturing the floor and comprimising it's integrity.


The glue used above in this thread is silicone based. It expands and contracts, giving you a sturdy and watertight edge around the tub.


I hope this has cleared up any issues you had.

Yeah, thanks, I have it figured out now, I didn't realize you were talking about nails/screws etc.


Thanks for clarifying.

Hi Joseph, I too am confused by your replies. You do show to adhere quater round moulding to planks using Liquid nails silicone based adhesive then later state to never glue moulding to floor only to vertical ( tub) surfaces. Tell me what you think of this solution. If one aplies any type of caulking or adhesive  between laminate and moulding this prevents laminate floors ability to move so if one were to apply thin layer of silicone to bottom side of moulding first, let dry, then adhere it to tub with adhesive followed by silicone caulking later this allows floor to move.
