The opening ceremony was performed on a Wednesday evening in May 1934 by Mr. H.S. Durbin JP and featured many displays of swimming, including an appearance by Miss Ivy Hawke, the successful 1928 channel swimmer. A water polo match was held, and the festivities went on into the evening.
The Lagoon was approached along a grass-lined entrance drive, On the other side of the road is a small stream, a tributary to the Hogsmill, and in front the whitewashed entrance with fittings picked out in bright blue paint. The photo shows the flats in Edith Gardens which are opposite where the Lagoon used to be. As visitors entered the pool complex through a turnstile they were greeted by an ornamental fountain. The pool had a full set of diving boards, both springboards and diving platforms at the deep end, and a simple tall slide. At the shallow end was a smaller slide suitable for children. Entry to the water was down a set of submerged stairs, an unusual design feature. Along the right hand side of the pool was a set of sun terraces, concrete broad stairs with wooden boards on top. There was a lagoon café, and an ice cream booth. Separate ladies' and gentlemen's changing facilities, each with a children's section. Ladies' facilities were on the left and gentlemen's were straight ahead, past the deep end. The pool was surrounded by a paved area, with the paving at the edge of the pool somewhat rough, making climbing out of the water without using the stairs an exfoliating experience. Though the water was heated, it was always a bracing experience to get in. The lagoon had a holiday camp carefree atmosphere:
"Surbiton Lagoon was an awesome place to be in the summer in the 70s. The moment you got through the turnstiles and saw that big fountain you could feel the excitement. It had huge terraces where you could sunbathe all day, the pool was massive with a really deep, deep end, the girls looked great in their bikinis. Baywatch in Berrylands. I know, let's knock it down and build another really boring housing development on it. Yeah, that's much better. Not! Massive, massive shame it was closed down. A shame on Kingston council. I feel it is sorely missed!" J Tait, New Malden
The tennis courts are now covered by a housing estate, the lagoon itself has been landscaped. The site was 20 acres, and the development cost was £18,000 in 1934.
