Cascading Water Wall at Sexy Fish Manchester

Caprice Holdings, the owners of Sexy Fish Manchester, approached SpaFlo to design and build a one-of-a-kind cascading water wall for their new restaurant opening, Sexy Fish Manchester.

Caprice Holdings is a collection of London’s favourite restaurants, a group which is constantly growing and evolving. Its restaurants are diverse, blending vibrant new brands with historic venues, some of which have been welcoming guests for well over a century.

Scientists have highlighted the significance of the sound of running water to human health and our general wellbeing. We tend to feel more relaxed when we are near waterfalls, rivers, lakes and oceans, so the addition of a water wall in an indoor space can bring indoors a greater sense of relaxation and serenity.

At Caprice Holdings, a leader in the high-end restaurant category, quality is key. When they approached the Special Projects Division at SpaFlo to design and build a fully-functioning cascading water wall for their new restaurant, we were thrilled. This water feature was to provide a magnificent backdrop for the bar where guests are greeted and first impressions are made.

Our passion for health through water, coupled with our expertise in building the highest quality bespoke stainless steel spas and pools, made SpaFlo the right people for this exciting project and we couldn’t wait to get started!

The SpaFlo Difference

The Sexy Fish Manchester project features a one-of-a-kind and never-before seen 7m x 5m fully functioning water wall as the central feature of its all new restaurant bar which opened in October.

The build showcases 3 unique areas of SpaFlo expertise:

  1. Overall scale - at 7m x 5m this is a huge - one-off piece of aqua engineering.
  2. Shape - wrapping what is effectively a U-shaped existing wall requires great technical knowledge of design, fabrication and installation.
  3. Build and Materials - the 3 key materials used; swimming pool plexiglass, marine grade stainless steel 316L and water require an expert level of competence.

Technical considerations of the project

The Plexiglass

The plexiglass was imported from Holland and lifted into position with a spider crane inside the restaurant. The largest individual piece of plexiglass was 5.0m x 1.75m x 30mm thick and weighed around 260kg’.

The project required four of these pieces to be jointed together to form the main wall.

Stainless Steel Troughs

SpaFlo manufactured patented overflowing weir details in 316L grade stainless steel for the upper troughs. The base collection troughs were also created in 316L grade stainless steel. Learn: the benefits of stainless steel.

The Plant Room

The plant room is on a mezzanine level in the basement floor below the main restaurant. Water is collected in a balancing tank in the plant room using a similar engineering practice to a swimming pool.

Three variable speed pumps (one for each wall) draw water from the balance tank and send it over a 20m of head journey back to the top of the waterwall.


We are using Endosan hydrogen peroxide as the sanitiser to eliminate all microorganisms from the water system. This is vital to keep the water running clear and clean.

SpaFlo designs and manufactures bespoke stainless steel hot tubs, spas, hydrotherapy pools and swimming pools for both commercial and private clients all over Europe. All of our designs are customised for the project in question and we have the expertise to work on one-of-a-kind projects like this too. We have made water walls, hot tubs for yachts and window-fronted hot tubs - get in touch if you have a project you’d like to discuss.
