LEDs under the edge of a raised slate shower tray. Good idea or bad?

Hi there,

I bought this 1500mm X 800mm X 30mm grey slate shower tray.

SLATE 1500x800 Shower Tray Black with shower waste

It will be installed on a raised bed of 2.5 inch concrete blocks, and I might put a sheet of 18mm Marine Plywood on top of those.

I have no choice but to raise the slate shower tray as it's an apartment building on an upper floor with a concrete floor.

I like the look of the LED lights here:

The example above is probably a tiled shower floor though, not a slate tray. If I do something like this could I overhang my shower tray by about an inch as illustrated here?

The problem with this is that people will be stepping from the bathroom floor tiles onto the black shower tray so there is a danger that the edge of the slate shower tray might get damaged. Any thoughts?

Here is another example:

Again that one is using a tiled shower floor. How would you approach this in my case where I have to use a slate tray (I've bought it now and won't change it)? Even if I wasn't putting in the LED light strip I'd need to tile up the front of the concrete blocks to blank off that area so maybe there is a way to do it by cutting an edge off the 2.5 inch blocks and tiling the top half of the block as shown here:

I'd appreciate your thoughts!

I have a second (related) question.

In the photo above you can see LED lights at the top of the shower. I'd like to do that also. Do you think adding these would cause issues with waterproofing / tanking? I know it's out of the immediate wet area but am I introducing a risk of damage from steam damage if I do that (note that there is no window in the bathroom but the extractor fan is directly over the showerhead)?

Thank you for your input guys!

Regards,
Dave

First option is fine just chemical stick the led profil to the tray before hand

Make sure you get the electrical safety aspects right.

Who is going to sign this off electrically ?

Shaun, thank you. Come to think of it I should be able to get an LED profile that is about half an inch wide so that's all I'd need to overhang the shower tray by. Maybe 3/4 inch if I put some waterproofing and a sliver of a tile standing on edge behind it.
I need to research how to chemical stick the profile, not sure about that bit.

Chuck, Murdoch, thank you for raising the critical issue of electrical safety. I am doing a complete bathroom remodel and will use a qualified electrician for any 240V work. These LEDs though are only 12 Volts, 72 watts, and are IP65 rated. They will be powered via a transformer which will be located in the nearby hotpress. Given that they are only 12V do you think I'd be okay to install those myself?

Note that I am in Ireland but our electrical and building regs are very similar to yours in the UK.

This is the link to the LEDs that I bought:

Looks like Plumbers Forum doesn't accept links to Amazon . co . uk so my link didn't come through. The LEDS are:

"Tesfish Super Bright 600 LEDs LED Strip Lights", but in any case the important point is that they are IP65 and 12V

Aslong as there ip rated I would say it’s fine and the drivers located where accessible and acceptable eg out side of zones
