Changing the shape of an indoor pool

An older indoor concrete pool reshaped to win back floor space, straighten an awkward footprint and make the whole room work.

A deliberate shape that suits the room instead of ignoring it.

The story behind the renovation

An outdoor shape running an indoor room

Plan of the pool before and after the shape change: the old freeform outline dashed, the new rectangle solid
The old freeform outline, dashed, and the rectangle that replaced it.

The pool was built outside in the seventies. A later owner extended the house and enclosed it, which turned a summer pool into a year-round one and left a freeform shape sitting inside a rectangular room.

When the property changed hands the new owners renovated the house and decided the pool needed more than a new surface. The curves left barely enough room to walk down one side, and the shape read as an accident rather than a decision.

We went through what was structurally possible and what was not, then cut the shell back and rebuilt one side to win floor space — keeping the parts of the pool that were sound and worth keeping.

The redesign took out the awkward curves and brought the pool into a controlled footprint without touching the depth.

What the photographs do not fully show

The new shape became part of the old shell

A shape change is structural work. What you see at the end depends on the join between the old shell, the new steel, the placed concrete and the finished interior.

Four stages, in order

How the old and the new concrete joined

Expose the original structure. The old surface and a section of concrete were opened up so the existing reinforcement could be reached.

Connect new reinforcement. New bars were anchored and lapped into the original steel rather than butted against it.

Form and place the concrete. Formwork set the new line, then fresh concrete was placed and vibrated so it compacted properly against the old.

Finish it as one pool. Old and new were finished as one pool, not left as visibly separate work.

Two structures touching move independently; one structure does not.

Experience built through real renovation work

Older project. Still relevant.

This job is years old now, but nothing about the method has changed: understand the existing shell, make a controlled structural connection, and decide the finished interior before the new concrete goes in.

It was one of our first substantial shape changes, and it is still the clearest example we have of the structural work that sits under a finished renovation.

A seventies pool cut back and rebuilt

Built outdoors in the seventies and later enclosed by an extension, the pool kept a freeform shape inside a rectangular room. One side was cut back and rebuilt to win floor space.

What went into the job

  • Old surface and a section of concrete opened up
  • New bars anchored and lapped into the original steel
  • Formwork set to the new line
  • Fresh concrete placed and vibrated against the old
  • Old and new finished as one pool
  • Light positions moved to suit the new profile

The result

A straighter line, proper access all the way round, and a new interior — with the skimmer, the main drain and the depth left as they were.

Came home from a two-week vacation and our pool was basically green. The previous company told us we needed to drain it, which sounded crazy. Pool Care LA came out, tested everything, explained what was happening and started the cleanup. Took a little time but now the water looks better than it has in years.Read in full

We had another pool company for almost five years and slowly the service got worse. They would say they came but the pool was always dirty. Jake from Pool Care LA has been completely different. He actually checks the equipment and lets us know if something needs attention.Read in full

Our pump stopped working on a Friday afternoon and we were worried because we had family coming over that weekend. Robert came out, found the problem and got everything running again. Honest guy, and he explained everything before doing the repair.Read in full

I don't usually leave reviews but these guys deserve it. My pool was a mess and I was tired of trying to fix the chemicals myself. They came out and took care of everything. Water is clear now and I don't have to worry anymore.Read in full

Bought a house in Beverly Hills with an older pool and honestly had no idea how to maintain it. The equipment was old and everything was confusing. They walked me through what needed to be done first and what could wait. No pressure. That was appreciated.Read in full

We thought we needed a completely new pool system. Turns out it was just a few issues with the pump and filter. They saved us a lot of money by fixing what actually needed fixing.

We have two kids and keeping the pool safe is important for us. Since switching to Pool Care LA the water has been consistently clean and balanced. It is nice knowing someone is actually paying attention every week.Read in full

What this Altadena shape change shows

Can the shape of an existing pool be changed?

Within limits, yes. This one was cut back and one side rebuilt to win floor space, keeping the parts of the pool that were sound and worth keeping. What is possible depends on the existing shell, which is why it has to be looked at first.

How does new concrete join an old shell?

Through the steel. New bars are anchored and lapped into the original reinforcement rather than butted against it. Two structures touching move independently; one structure does not.

Does a shape change mean losing depth or moving the plumbing?

Not necessarily. Here the overall depth was maintained, the original skimmer stayed in its place and the existing floor drain was kept. Only the light positions moved, to suit the new profile.
