People are becoming more mindful about what goes onto their skin, into their bodies, and even how their homes are designed. However, many cleaning products still rely on harsh chemicals, industrial-style formulas, and overpowering synthetic fragrances. A new collaboration between Bali wellness brand Utama Spice and design-led bathroom specialist Ahti Interiors aims to change that through a new range of home care products combining high performance with natural and environmentally friendly formulations.
The collaboration brings together two brands approaching modern living from complementary perspectives. For more than 30 years, Utama Spice has focused on plant-based wellness, essential oils, and Indonesia’s traditional botanical knowledge. Ahti Interiors, named after the Finnish god of water, curates premium sanitary ware for Indonesia’s leading residential and hospitality projects, with a design philosophy rooted in functionality, clean aesthetics, and material-conscious simplicity.
Together, the brands are rethinking home care through products that are effective and practical, while also being gentler on the home environment and better suited to contemporary living.
“Home care products are usually treated as purely functional, so there hasn’t been much attention paid to the ingredients they contain,” said Ria Templer, Director of Utama Spice. “We wanted to create products that are highly effective without relying on unnecessarily harsh chemicals that can damage surfaces and be harmful for people and the planet.”
The first product from the collaboration is a plant-powered limescale remover designed to break down hard water stains and mineral buildup using a triple-acid system combining citric, gluconic, and lactic acid. Limescale is a common issue in many Indonesian bathrooms, particularly in areas where groundwater contains high levels of natural minerals that gradually accumulate on tiles, shower glass, taps, and fixtures. The formula also incorporates biodegradable plant-based surfactants and essential oils, offering heavy-duty cleaning performance without the aggressive chemicals associated with many conventional bathroom cleaners.
One of the product’s key features is that it is brass-safe, which is uncommon for many powerful limescale removers that can damage fixtures and finishes. The product was designed specifically for modern bathrooms and material-conscious spaces, combining Ahti Interior’s expertise in architectural bathroom environments with Utama Spice’s experience in natural ingredient formulation.
For Ahti Interiors, the collaboration reflects a broader shift in how people think about the spaces they live in.
“Bathrooms today are no longer treated as purely functional spaces,” said Erica, Marketing Manager of Ahti Interiors. “People invest in natural materials, carefully selected fixtures, and spaces designed to feel calmer and more comfortable to live in. We felt the products used to maintain those spaces should reflect the same level of care.”
The collaboration also taps into growing interest in products that bridge wellness, design, sustainability, and functionality. While environmentally friendly cleaning products have existed for years, few brands in Indonesia have approached home care through both a formulation and lifestyle perspective — balancing performance, material compatibility, and design-conscious living within the same product category.
With additional products in development, the collaboration reflects growing demand for home care products designed not only to clean effectively, but also to better respect the spaces, materials, and people around them.
The first product from the Ahti × Utama Spice collaboration, Limescale Remover, will be available in Utama Spice stores and online from the end of May 2026.
