Upgrading the bathroom lights is well worth the effort. It takes quite a long time and a bit of soldering is involved if you want the concealed lighting look.
With a few basic tools, it is possible.
Tools and Materials
Waterproof LED Lights Warm White - amzn.to/2TFzgIm
Multimeter - amzn.to/2TEHyjm
Snips - these are the ones I use which are excellent but expensive - you can find ones way cheaper - amzn.to/2IBKmYi
Wire strippers - I use this type which can be adjusted for a wide variety of wire thickness - amzn.to/33ag4Fx
Soldering Iron - I use a gas soldering iron so I don't need the power to use it but a gas one is not essential. They don't make the one I use anymore. There are a lot of good starter kits available at a very reasonable cost - amzn.to/2vRNrAI
Plumbers gold - amzn.to/3cI8Blw
Sikaflex - I use the 512 - its really good stuff - amzn.to/2TNx6Fi
