This is an ongoing project and this page is being updated regularly.

Background

Niel contacted buildahottub.com in early August 2020 after he had been following the instructions for how to build your own DIY Hot Tub. Niel is a competent DIY’er – you’ll see some of his pictures below and the block and brickwork as well as his concrete slab were very well made indeed. He certainly didn’t need any help with this side of things! Niel contacted us because he was a little unsure on the plumbing side of the build.

He had been following the brickwork and ground prep that we describe in the “How To” page that Andi wrote. What Niel couldn’t get his head around was the plumbing side of things. Instead of making some costly mistakes, Niel got in touch.

Initial Contact

Niel made contact with Andi over the online chat on www.buildahottub.com initially to thank him for all the info that he has put on the site. The pair began to chat and Andi answered some of Niel’s initial questions. He then offered to draw up the plumbing plans for Niel when they identified that this was the area Niel was struggling with.

It wasn’t just the plumbing diagrams that Andi helped with, he converted Niel’s PowerPoint sketches into full 3D modelled CAD. This then enabled Niel to visualise the build a little bit better. On the back of this, he also changed the design slightly and moved the step positions.

The 3D model also helped with discussions on where jets were going to go, light placement – things that were just a bit too difficult to visualise from the powerpoint sketch.

Scope of Work

The scope of work for Andi and www.buildahottub.com is the custom design of the hot tub, plus full plumbing diagrams for Niel as well as supplying the plumbing parts.

Early August 2020

This is very much the “before” shot of Niel’s garden.

The mini digger made light work of digging the hole and clearing the area – much easier than the back=breaking way Andi dug his!

A bed of type 1 was “whacked” flat

The base was lined and then filled with metal rebar for additional strength. Beautiful work here Niel!

The slab was then poured.

September 2020

A retaining wall was put in but then Niel hit a little bit of a roadblock!

The dividing wall with his neighbour was too weak and was beginning to crumble. With a young family, it was just not worth taking the chance so Niel has had to put development on the Tub on hold whilst he pulls back and rebuilds the wall first!

October 2020 – Just Call Him “Mr Blockwork”

The last few weeks have really seen the weather turn in the UK. It was as if someone had flicked a switch. We went from sun and pleasant temperatures to rain and chill overnight! So now, Niel has the UK weather to contend with as well. Needless to say, progress on Niel’s build has been slow. I mean, how are he take a couple of weeks off to go on a family vacation! Hope a good time was had by all!

Anyway, back to the build and “Mr Blockwork” is back in action repairing the boundary wall between him and his neighbour. If that job in finance goes down the pan, you’ll have no problem as a bricky! Once again, stunning work Niel and this one is certainly not going to fall down – just take a look at the beautifully made foundations! Niel plans to clad and tile this one the tub is in place and I am sure it is going to look fantastic.

Looking good Niel, mind your step!

November – December 2020

After completing the external clockwork and putting in the lower block work for the seating, it was time for Niel to bore some holes. As you can see from the pictures, Niel invested in a pretty heavy duty hammer drill along with some core-drill bits. I think he said he got a good deal on them on Black Friday. They certainly look the part.

The next task for Niel is to core out all of the holes for the lower drains and also the gunite bodies.

With the weather taking a turn for the worst this time of year, progress is slow. The Christmas holidays were upon Niel in no time but with a young family, there are more important things to do this time of year than to be boring holes in cinder blocks!

January 2021

After a very cold and wet Christmas break, Neil has picked things up again but progress is slow due to the weather. Niel has drilled the holes for the gunite bodies and then threaded through the 2.5″ outer pipe from outside of the tub into the footwell for his lower jets.

To try and reduce the heat loss, he is going to insulate the seating area with celotex insulation.

With a bit of luck, this will help reduce the amount of heat lost and in turn, allow Niel to make some savings on the running costs.

Finally, Niel has backfilled the seating area. You will see that he has changed his design a little in that now, there is seating just on three sides. This is because his wife wanted to have more space for his young family to learn how to swim in the Hot Tub – how cool is that!

Keep up the good work Niel, this is coming along nicely!

Do You Need Some Help with your DIY Build?

If you need some help with your build then let us know. Drop us an email at andi@buildahottub.com or use the chat. We can help with plumbing designs. We can supply the specialist parts that you need. We can even convert your sketches into 3D CAD so you can better visualise what you are trying to build. Take a look at our plan options here.
