Liquid Laundromat Trentham is a self-service laundromat located at Trentham Mini Mart in Heretaunga, Upper Hutt, part of the wider Liquid Laundromats network across New Zealand. The location is open 7 days a week, 24 hours a day, giving customers a flexible, self-service option that works around their own schedule rather than fixed opening hours.
The laundromat is fully cashless, running on the Liquid Card system rather than coins. Customers can purchase and top up a Liquid Card on site using Eftpos, Mastercard, PayWave or Visa, and the same card works at any Liquid Laundromat location around the country. Machines include small, large and super large "High Spin" washers, which extract more water than standard machines so clothes dry faster, along with small and large dryers. The super large washers are suited to bulky items such as king duvets, mink blankets and curtains, and dedicated pet washers are available separately for pet blankets and bedding, keeping the regular machines hair-free for clothing customers.
Liquid Laundromats describes itself as an upgrade on the old-style coin-op laundromat experience, with industrial machines up to three times faster than standard home whiteware, high-efficiency water and energy use, and precise temperature controls across cold, warm and hot settings to suit different fabrics and soil levels. The company is a New Zealand family-owned and operated business, not a franchise, and is a proud supporter of KidsCan.
Tucked into the Trentham Mini Mart in Heretaunga, Upper Hutt, Liquid Laundromat Trentham gives locals a self-service laundry option that never closes — the site is open 7 days a week, 24 hours a day, so there's no need to plan a load of washing around store trading hours.
Liquid Laundromats markets itself as a step up from the old-style, dimly lit coin laundromats many Kiwis grew up with. The machines here are described as industrial-grade and up to three times faster than a standard home washer, with "High Spin" technology that extracts more water during the wash cycle — meaning clothes come out of the washer already closer to dry, cutting down time in the dryer as well.
Instead of feeding coins into a slot, Liquid Laundromat Trentham runs on the Liquid Card system. Customers buy a reusable card on site for a one-off cost, then top it up using Eftpos, Mastercard, PayWave or Visa in $10 increments, up to a maximum balance. The same card works at any Liquid Laundromat location around New Zealand, so it's not tied to this one site — useful for anyone who splits their time between Upper Hutt and elsewhere.
Machines range from a small 8kg washer, good for a week's worth of clothes, up through an 18kg large washer suited to families or towels, to a super large 28kg washer built for genuinely bulky loads — king duvets, mink blankets and curtains all fit. Each washer offers a warm/hot or cold wash setting, with a heavy duty option for particularly soiled loads. On the drying side, small 14kg and large 22kg dryers are both available, with the option to pay to extend drying time if needed.
For pet owners, Liquid Laundromat Trentham offers dedicated pet washers, kept entirely separate from the machines used for clothing. That separation matters — regular customers get hair-free machines for their clothes, while pet blankets and bedding get their own equipment designed for the job.
The wider Liquid Laundromats network offers some practical guidance that applies here too: don't overload the washer, since laundry needs room to move for a proper clean, and avoid overloading the dryer as well — a lighter load in the dryer tends to come out with fewer wrinkles, which can save an ironing session altogether. Cold settings suit dark colours and delicates, warm suits synthetic blends and moderately soiled clothes, and hot is recommended for heavily soiled items, bedding and towels where maximum sanitation matters. A typical wash cycle takes roughly 25 to 30 minutes, depending on load size and the cycle chosen.
Liquid Laundromats is not a franchise — it's a New Zealand family-owned and operated company, with locations spread around the country including Trentham. The company is also a proud supporter of KidsCan, the New Zealand charity supporting children in need.
For anyone in Heretaunga or wider Upper Hutt needing to get a big pile of washing done fast, without needing coins or being tied to store hours, Liquid Laundromat Trentham offers a straightforward, round-the-clock option.
