Zinc tub garden pond safety

Updated: October 2026

You are about to fill a shallow metal tub for a water lily or a small solar fountain, and the tub looks too small to count as a pond. It counts. Zinc tub garden pond safety starts from the water, not from the word pond. RoSPA says a child can drown in a few centimetres, and the shallow tubs in the [zinc tub comparison](/hub/swimming-pools/zinc-tub) are about 15 cm deep, with one pan about 29 cm high. If a small child can reach the garden, the safe choice is often to empty the tub and turn it over. The Products Compared editorial team set this out on 16 October 2026 from RoSPA, the Royal Life Saving Society UK, the RHS, and the amazon.co.uk captures. There was no safety trial of these tubs. A qualifying purchase can earn a commission at no extra cost to you.

A shallow tub is still water

The Esschert OZ70 is the clearest shallow example in the file: about 59 cm by 45 cm by 15 cm, 21 litres, £24.99. The maker page describes that oval zinc tub. The amazon bullets describe a hanging bracket, which is the wrong object, but the size you would put on the patio is still about 15 cm of water if you fill it. The MAISONICA is the same footprint class, 59 cm by 45 cm by 14.8 cm and 14.66 litres, at £26.45, with no review line and no star rating to quote. The pan tub is taller, about 29 cm high and about 49–55 cm across, at £44.99. UK reviews of that pan mention a water lily, a frog pond, and a small solar feature. One UK review says it leaked. A leak does not make it safe. A tub that holds is the hazard. A tub that fails the water test is a different problem, not a childproof one. RoSPA’s pond guidance is written for garden ponds, and it still binds a tub you could step over. The charity says garden ponds are involved in 26% of child drownings in the home. Its outdoor guidance tells you not to leave children unattended at a paddling pool, and that a few centimetres of water are enough. Fifteen centimetres is not under that line. Twenty-nine centimetres is not under it either. A raised rim, a lily pad, or a solar pump does not cancel the depth. The RHS says even a mini container pond is a hazard for young children, and that you should place the container before you fill it so you are not walking with a full tub. This page is not a stock-tank review. Those tanks start around £390 and are large enough to sit in. A 15 cm zinc tub is a container of water. Treat it as one.

What to do while the water stays

If you decide the water stays, you take the steps RoSPA lists for a pond, scaled to a tub you can actually cover. Supervise young children whenever they are in that garden. A rigid grille over the water, fixed so it cannot be lifted off as a game, is one of the options RoSPA names. Chicken wire is not that grille. It sags, it tears, and it is not the recommendation. A fence of 1.1 metres with a self-closing gate you can lock is the other structural option RoSPA gives for a garden pond. A tub on a patio is often easier to empty than to fence. The grille or the fence is for the case where the lily pond is a fixture you refuse to drain. The RHS also asks for a wildlife ramp, so a frog is not trapped in a smooth tub. That ramp is for animals. It is not a claim that a child can climb out. Rainwater is what the RHS prefers in a wildlife container, after a leak test, and it is still water a child can fall into. Do not drink it or top up a pet bowl from it. The Drinking Water Inspectorate’s line is blunt: a lily tub is not an approved drinking-water store. Position the tub before you fill it. A full Esschert-sized tub is an awkward lift, and a full pan is worse.

Empty it when the garden is a child’s garden

If small children visit, or live there, the RLSS UK garden advice is the one that fits a tub: empty containers and turn them over. A bucket, a paddling pool, and this zinc tub are the same habit. RoSPA’s strongest pond option, where the risk is not acceptable, is to fill the pond in. You cannot fill a tub into the lawn, but you can empty it, turn it over, and store it so rain does not refill a bowl. Do that at the end of the day, not only at the end of summer. A tub that held a lily in June is the same tub in a wet October. Do not invent a safe depth. RoSPA’s few centimetres leaves no band in which a 15 cm tub becomes a toy. The grille and the locked gate are for water you insist on keeping. The turned-over tub is for water you can live without while children are around. A solar fountain switched off is still a bowl of water. A cache pot with a puddle of rain is already this problem in miniature. Zinc tub drinks or planter keeps holes and ice apart. It does not clear a closed tub of water for a toddler. Empty a party tub when you bring the bottles in. Drying the metal is on how to use a galvanised ice tub. Drying removes the water, which is the safety step as well as the rust step.

Which tub, and what to do in an emergency

Use this page with the garden rows. The Esschert OZ70 at £24.99 is the shallow oval whose maker page matches a tub. Amazon bullets describe a bracket, and drainage is not stated, so a water test tells you if it holds. The MAISONICA at £26.45 copies the footprint, with no reviews and a round-versus-oval clash. The pan tub at £44.99 is the one UK reviews use as a lily pond, at 4.4 from 14, and one of those reviews says it leaked. About 29 cm of water is a deeper version of the same risk. None of these is a stock tank or a product cleared for unsupervised play. Capacity and the bracket bullets are sorted in the galvanised tub buying guide. A drinks tub full of meltwater on the grass is still water. If a child has been under the water, call 999. RoSPA says to get medical advice even if the child looks well. Do not wait to see if they perk up, and do not spend the first minute measuring the tub. Empty it afterwards.

Common questions

Is 15 cm deep enough to be dangerous?
Yes. RoSPA says a child can drown in a few centimetres of water, and it tells you not to leave children at a paddling pool. The Esschert-sized tubs in this file are about 15 cm deep. The pan tub is about 29 cm high. Neither depth is a free pass because the tub is metal, raised, or planted with a lily.
What should I do with the tub when children are in the garden?
Empty it and turn it over so rain cannot refill a bowl. That is the RLSS habit for garden containers. If the pond is a fixture you will not drain, RoSPA’s alternatives are a rigid grille that cannot be lifted off, or a 1.1 metre fence with a lockable gate, plus supervision. Chicken wire is not the grille.
Is chicken wire enough over a small tub?
No. RoSPA specifies a rigid grille, properly secured, not chicken wire. Wire sags into the water and is easy to push down. A small tub is easier to empty than to cover badly. If you cover it, the cover has to stay fixed when a child leans on it.
Can I drink the water or top up a pet bowl from it?
No. A lily tub is not an approved drinking-water tank. The Drinking Water Inspectorate says drinking water wants a proper covered cistern, and old galvanised storage can rust and taint water. Rainwater in a wildlife tub stays in the pond.
Who do I call if a child has been under the water?
Call 999. Then get medical advice even if the child looks well. That is RoSPA’s instruction. It does not change because the water was in a tub. Empty the tub afterwards.
