I'm looking into slowly updating my 1957 blue bathroom in my home. One thing I'd like to get out of there ASAP is the old, original vanity with blue sink. (Half of the vanity underneath is actually a hamper, so it doesn't have great storage. It's also been painted over multiple times.)

We have a large vanity space, around 51" or so. I am exploring options to replace the vanity, but vanities of this size (mostly looking at 48" for price points) are quite expensive ($1,000+).

Has anyone installed an Ikea vanity at least 2+ years ago, and can speak to the results of how well it holds up? I worry about the quality, especially because our bathroom doesn't currently have a fan/vent, and the window is also original to the home so there is a lot of moisture that collects there (no screen, and we have cats, so we can't really leave it open more than a tiny crack). I am not sure if the fiberboard of the Ikea vanity would hold up well in this type of environment. We want to install a fan long term, but can't afford to do so right now.

For reference, I'm considering an Ikea vanity such as this one, vs. a vanity from Lowes (which is made of real wood & "wood veneer construction"). Thanks for any input.
