Tehila is excited to bring you a new line of utility sinks designed with the customer in mind. Tehila Basics. Our extra deep sink tub is bigger than any other equally priced utility sink on the market. The sink tub is made of high-quality durable thermoplastic and features a stain-resistant wipe clean surface. Sturdy rust-proof steel legs attach easily, and the included floor levelers increase stability. Adjust foot levelers to the perfect height to level the tub on bumpy or uneven surfaces, perfect for a laundry room, basement, or industrial workshop.
