Submerged swimming pool lights are designed to be built into the pool walls as they are being constructed - they are safe for swimmers because they are recessed into the pool wall. An underwater battery operated light would have to be fixed to the pool wall and would be a safety hazard for swimmers. All modern pool lights are 12 Volt and power is provided by a cable to a 240/12 volt transformer in the pool control panel. Lights can be installed retrospectively but the pool would have to be emptied down to the light level (about 500 mm below the water surface)

Hi Fortune, Even the simplest pools that I have worked on professionally, we have always hired a pool company / expert to work alongside with, so definitely do your research to find a good one you like (Or search some here). From a professional perspective I can give you the following guidance having designed and worked on a around five indoor pools, some super lux and others just normal. 1. Get clear on your design and don't change your mind - this will cost you probably quite a lot especially if they have started work already (don't forget that most things you see with pools are hidden). 2. Don't cut costs on heating (water & room), drainage, pool systems, tanking, filters and pumps. You WILL have to fix it over and over and it will always be a thorn in your side. And always listen to the requests for access panels (undoubtedly you WILL eventually need access to absolutely everything). 3. You will most probably need to hire a M&E consultant or a ventilation company separately to deal with the air inside if your pool company doesn't already cover this. 4. Try to cut costs and save money on the external structure and finishes. There are an unlimited number of ways to design a nice pool enclosure - don't get stuck on one way, especially if you are on a budget. Get clear on one idea (fireplace at the end or pitched roof, or glazed end and see that through - your costs will explode if you start believing you need everything. One feature will work - make it special, and if you cant live without the others, put in provisions but save for them later). Don't forget tiling and finishes will need to have slip ratings. 5. Don't forget that glass (and mirrors) if not heated will fog up, spoiling your view out of windows. 6. Don't forget to think about the lighting (and maintenance of it - especially if it is above the pool). 7. Keep all of your warranties in tact and in a safe place - (You will most probably need them). This is the end of my professional guidance! (Change of voice with an Aussie twang) ------The below should not be taken as professional advice or guidance in any way---- Now as an Aussie having worked on way too many pools that I think wasted a lot of money for absolutely nothing and having spent 28 years of my life swimming in millions of different pools, this is what I actually wanted to write to you! 1. I would totally explore European and Eastern European pools. Just like I would trust an Aussie company (but still use your brain, there are always duds amongst the good ones). 2. Never underestimate how strong the smell of chlorine is - you will smell it at least 10 metres away, behind air lock doors and even outside of the building (and don't let anyone tell you otherwise). 3. Salt water pools are superior and worth the investment. (My humble Aussie opinion). 4. Don't choose any plastic finishes for drains that are visible, they look cheap and tacky. There are some fantastic better quality ones (from Australia of course) - check out Aqua Bocci for drainage - its available here too. 5. Also, don't choose plastic edging strips for anything, not sure why these even exist on earth, no matter how expensive everything else is, it will look cheap and its one of the things you will always see. Think about the details and search online for how tiles are finished - there is always a way. 6. Consider an outdoor pool with a roof that closes and opens. Teamed with a good pool cover (electric of course) it could possibly be a much better solution depending on the location. I have always wanted to use Umbris, but haven't had a chance on a project yet! I hope this gave you a head start! P.S, I checked your idea board - your ideas for your pool are absolutely divine! I hope this helped because it would be a pity for such wonderful ideas not to become real! Jo and some pretty pics below, just because...

I did a search for garden pod buildings and amongst a lot of others, this one came up. It has prices on the website, so it will at least give you a sort of guideline of what a building like that would cost. https://www.smartgardenoffices.co.uk/?gclid=Cj0KCQjwvabPBRD5ARIsAIwFXBlhJvpztz64gP5jL7i6B3-nbbf01CdDfES4_-_M9d-6AZuuo_HXUzkaAk25EALw_wcB

The pool man was going to leave it like this. then he said could cover the blocks with mosaic tile. But I think the gap is too big and I don't like the blocks. so he said we can add extra marble and stick it underneath the present marble OR add 2 squares of the mosaic tile underneath the present marble , so the gap is less ,but I think I 'll still be able to see the blocks.
