Caulking outside plinth edge

[LJB179]

Hi All,

I would love to get some help. I’m a total amateur DIYer, but comfortable caulking inside edges. I’ve got an issue though - I had a renovation done and my builder whacked the plinth outside of the bath tub. Now, this may have been fine but the awful plinth that came with the board isn’t very waterproof and is cracking up badly. Looks terrible and at some point I’m worried it’ll come apart.

I thought about simply applying duct tape, then I tried the silicone sealing tape stuff, however, it was huge and ugly so I ripped it off. So, I ask you kindly, is there a way to caulk this outside edge effectively to cover the cracks (so it doesn’t look super ugly and maintains). It gets occasional water on it due to the shower but I think it’s mainly coming apart due to moisture. I’ve attached a couple of photos!

NB. My builder has attempted to caulk this twice and was unsuccessful, although this might be due to him not really understanding the issue.

Thanks in advance!

What size plastic L would fit that?
You can lay down and cut although it takes time cutting from the back by continually striking the knife along.
Stick it in with silicone.
Use masking tape to prevent silicone from spreading then pull masking tape.
Keep the silicone where you want it.
Maybe you need some silicone removed on what you have there now to tidy.


I was thinking of something like

Better to buy correct size if you can

thanks, that could be a good solution. The actual L, width wise, is tiny, 1cm in the widest parts. One challenge is that the bath bows a bit, and the plinth too, so it isn’t a consistent width. Of course, I could cut it, however, I don’t know whether it’d look great. Covering with silicone though would maybe help with how it looks. The length is 143cm, so I’d just need to cut that down, which I’m sure I could do.

You can do this sort of thing.
