On the first day of production, May 31, Universal's operating committee decided that because of the type of special photography involved in the making of the film, the publicity department would cooperate by publicizing a closed-door policy on the set. On-set photography would not be allowed while the film was shot to stimulate public and trade interest.{{sfn|Lucas|2017|loc=00:16:57}} Shooting took either five or six weeks, including the special effects sequences. The budget ranged between $700,000 and $800,000.{{sfn|Warren|2009|p=402}} Film critic [[Kim Newman]] said the budget was "not expensive", with  most of it used for special effects.<ref name="tism-9">{{Cite AV media notes| title =Robinson Crusoe in His Own Basement | last =Newman| first =Kim |author-link = Kim Newman| year = 2017| page = 9| type =booklet| publisher = Arrow Films| id = FCD1628}}</ref>

Some special effects shots were the earliest taken for the picture. For example, shots with Randy Stuart were taken against a black velvet backdrop and then composited with shots of Williams on an enlarged living room set. Their movements were synchronized using negatives from the first exposed scene in the camera gate, with the opposite done for the other scene.{{sfn|Lucas|2017|loc=00:20:48}} Sound production began on May 31.{{sfn|Lucas|2017|loc=00:05:34}} An oversized dollhouse was built for Williams on Stage 28. It had previously been used for ''[[The Phantom of the Opera (1925 film)|The Phantom of the Opera]]'' and ''[[Dracula (1931 English-language film)|Dracula]]''.{{sfn|Lucas|2017|loc=00:31:03}} Arnold said he filmed scenes with the cat in a normal studio with an animal trainer who had about 40 identical cats.{{sfn|Lucas|2017|loc=00:33:40}} To coax the cat to approach the dollhouse, Arnold hid food in it so the cat would find a way into the house.{{sfn|Lucas|2017|loc=00:34:00}} Later he timed the cat's reactions and directed Williams accordingly to react to the cat.{{sfn|Lucas|2017|loc=00:34:00}} Arnold first attempted to follow the novel and use a black widow spider. After preliminary tests, he found black widows were too small to use properly in the film.{{sfn|Lucas|2017|loc=00:49:20}} In an interview with Tom Weaver, Randy Stuart said the spiders presented problems. The overhead lamps on the set had to be turned up high, leading to the deaths of 24 tarantulas.{{sfn|Warren|2009|p=405}} They were directed with little puffs of air, a technique which had been used previously in Arnold's film ''[[Tarantula (film)|Tarantula]]''.{{sfn|Warren|2009|p=405}} Despite sources suggesting otherwise, the films did not use the same tarantulas.{{sfn|Warren|2009|p=405}}<ref name="afi" />

Many of the basement scenes were shot on Stage 12 of Universal Studios which, according to Tom Weaver, was one of the largest [[sound stage]]s in the world at the time.{{sfn|Lucas|2017|loc=00:38:39}} While trying to find a way to simulate giant drops of water landing, Arnold recalled a time when he was a child and found condoms in his father's drawer. Not knowing what they were, he filled them with water and dropped them.{{sfn|Lucas|2017|loc=00:41:05}} Arnold ordered about 100 condoms and placed them on a treadmill so they would drop in sequence.{{sfn|Lucas|2017|loc=00:41:05}} The flood scene was shot on July 2 and 3.{{sfn|Lucas|2017|loc=01:03:55}} There was a 20-minute delay in filming because of a bad camera cable. There was a further delay from 11:05&nbsp;am to 11:25&nbsp;am to allow water to drain so a crane could be used properly.{{sfn|Lucas|2017|loc=01:04:30}} These scenes involved nine-hour workdays. When the actors were not filming, they were sent to have publicity shots taken.{{sfn|Lucas|2017|loc=01:04:30}}

The film was originally shot in the standard 4:3 [[Aspect ratio (image)|aspect ratio]], but midway through filming, on June 22, it was decided that the remaining footage would be shot in 1.75:1. The belief was this would give the film a better look, as a shorter frame would allow the production department to scale down the height of certain props for the special effects.{{sfn|Lucas|2017|loc=00:37:32}} During this period, Grant Williams suffered the first of many injuries on set. On June 22, he reported to the studio hospital with a scratched leg; on June 29, he had to leave the set to be treated for an eye condition; and on July 2 he both had to be driven to the hospital for further treatment for his eyes{{sfn|Lucas|2017|loc=00:56:05}} and was sent to the studio hospital with blisters and scratches from climbing sets.{{sfn|Lucas|2017|loc=00:57:15}} Due to Williams' injuries and some special effects shots being too bright, the film was four days behind schedule and $25,000 over budget.{{sfn|Lucas|2017|loc=00:57:15}}
