Just got a Kohler acrylic bathtub delivered. Everything looks perfect except for this chip on the edge - https://imgur.com/a/R4xi8fm

enter image description here

It will be covered by the tile, but is there a chance it could cause a crack or any other issue in the long run? It's my second try already, the first bathtub had a major defect. I would not want to go through the return again if this is fairly normal and won't evolve in a crack over time

    Looks like their quality control person got out sourced. I think it is just cosmetic, but I am not a bathtub expert. It should be returned for not being perfect, but it is up to you. I would write a letter to the big rigs.

  • @Ruskes Think that is more of the site being stupid. I am glad to be over 18 to see a picture of a bathtub. It does not even show the good bits.

  • What are the dimensions of the chip? And the tile thickness. It looks like similar in size to the thickness of tile+adhesive, too close for comfort in terms of getting everything sealed and even. But without numbers it's a guess

As long as the chip will be covered by the tile/sealant by at least 3mm or 4mm (5/32nds of those inches things?) you should be good to go. Generally chips don't 'spread' and the underneath material is also water resistant.

  • My worry was that you're asking more of the sealant in that spot - with thin tiles you won't get that overlap and you might need to build it up. The bath is made of waterproof materials but the wall probably isn't

    I tend to agree that this is probably harmless. I would still make the vendor take it back and deliver an undamaged unit, if I could afford the delay.

    Thank you for the answers. My porcelain tile is 1/2 in thick. I decided to keep the tub since Homedepot offered $150 compensation for the imperfection
